英语的造字的逻辑 -回复

英语的造字的逻辑-回复什么是马尔可夫链?马尔可夫链是一种数学模型,用于描述具有马尔可夫性质的随机过程。
它由一系列状态和状态之间的转移概率组成。
马尔可夫链的特点是“无记忆”,即在任意给定状态的情况下,未来状态的概率仅仅取决于当前状态,而不受过去状态的影响。
马尔可夫链的定义:1. 状态空间:马尔可夫链的状态集合,用S表示。
2. 初始状态分布:马尔可夫链在时间0开始时,处于某个状态的概率分布,用π表示。
3. 转移概率:表示状态之间的转移概率,用P表示,其中P(i, j)表示从状态i转移到状态j的概率。
一个马尔可夫链可以用状态空间S、初始状态分布π和转移概率矩阵P三元组来表示。
马尔可夫链的性质:1. 马尔可夫性质:在任意给定状态的情况下,未来状态的概率仅仅取决于当前状态,而不受过去状态的影响。
2. 连通性:对于任意两个状态i和j,存在一系列状态k1, k2, ..., kn,使得P(i, k1) ×P(k1, k2) × ... ×P(kn, j) > 0。
3. 不可约性:对于任意两个状态i和j,存在一系列状态k1, k2, ..., kn,使得P(i, k1) ×P(k1, k2) × ... ×P(kn, j) ≠0。
4. 遍历性:从任意状态i出发,经过有限步转移,可以到达任意其他状态j。
5. 马尔可夫链的平稳分布:如果存在一个概率向量π使得πP=π,那么π就是马尔可夫链的平稳分布。
马尔可夫链的应用:马尔可夫链在许多领域都有广泛的应用,例如自然语言处理、机器学习、金融、医学等。
下面以自然语言处理为例,介绍马尔可夫链的应用。
在自然语言处理中,马尔可夫链经常被用来生成文本。
假设我们有一个语料库,其中包含大量的句子。
我们可以将每个句子看作马尔可夫链的一个状态,状态之间的转移概率可以通过统计句子中每个单词的出现情况来计算。
使用马尔可夫链生成文本的步骤如下:1. 首先,从语料库中选择一个初始句子作为起始状态。

The Primakoff effect on a proton target

a r X i v :h e p -p h /0502233v 1 25 F eb 2005The Primakoffeffect on a proton targetget 11Thomas Jefferson National Accelerator Facility,Newport News,Virginia 23606(Dated:February 2,2008)Primakoffeffect offers us with a way to determine the radiative decay width of pseudo-scalar mesons when they are photo-produced in the electromagnetic field of hadronic systems.Taking advantage of recent developments in the Regge description of the production of mesons in the strong hadronic field,this paper evaluates the relative importance of the electromagnetic and the strong amplitudes,and assesses the possibilities which become opened by modern experimental facilities.PACS numbers:13.60.Le,12.40.NnThe study of the Primakoffeffect [1]in the coherent photoproduction of pseudo-scalar mesons on nuclear tar-gets has been recently completed at JLab [2]and will greatly benefit of its energy upgrade to 12GeV [3].The production of a meson in the Coulomb field of the nuclear target gives a direct access to its radiative decay.A pre-cise knowledge of the π◦meson radiative decay provides an accurate test of chiral anomalies and mixing effects due isospin breaking by the difference of the masses of light quarks [4].The precise measurement of the radia-tive widths of the ηand η′mesons will lead to an absolute determination of their other decay widths,which are usu-ally measured relative to the radiative decay width.A better understanding of the (π◦,ηand η′)system will result in the determination of the mixing angles which quantify isospin and SU(3)symmetry breaking [4].However,the mesons can be concurrently photopro-duced in the strong nuclear field.This hadronic inter-action is mediated by the exchange of vector mesons (ρand ω)whose singularity is more distant to the phys-ical region than the singularity of the photon which is exchanged in the Primakoffamplitude.Consequently,the strong amplitude contributes to large production an-gles,but its tail must be subtracted from the Primakoffamplitude which contributes at smaller angles.In previ-ous pioneering experiments [5,6],this has been achieved by parameterizing the experimental yield at large angles and extrapolating it below the Primakoffpeak.While this procedure led to a radiative decay width of the π◦meson in good agreement with the value deduced from collider experiments,it led to a radiative width of the ηmeson about two times smaller [7].The quality of the beam of CEBAF at JLab,together with the improvement in the experimental set-up,permit the study of the Primakoffproduction of pseudo-scalar mesons,and the determination of their radiative decay widths,with an unprecedented statistical,as well as sys-tematic,accuracy.Mastering the hadronic contribution becomes mandatory.This note is an attempt to deter-mine the relative importance and the interplay between the Primakoffand the strong amplitude on the simplest target,the proton.It takes advantage of the latest de-velopments [8]in the Regge description of the photopro-duction of π◦and its extension to the ηand η′sectors.1010110d σ/d t (µb /Ge V 2)FIG.1:duced in the reaction p (γ,π◦)p ,at E γ=5.8GeV.The dashed curve corresponds to the hadronic cross section,while the full curve corresponds to the coherent sum of the electromagnetic and the hadronic amplitudes.The sign of the electromagnetic amplitude has been changed in the dotted curve.Let us start with the π◦production channel.Fig-ure 1summarizes the results at E γ=5.8GeV,where experimental data [9,10]exist.The cross sections are plotted against the squared four-momentum transfer t =(k γ−p π◦)2between the incident photon (k γ=(E γ, kγ))and the outgoing meson (p π◦=(E π◦, p π◦)).Since the en-ergy is large and the mass of the π◦is small,the minimum value,t min ,of −t is very small and the Primakoffpeak is well separated from the hadronic peak.The experimen-tal data seem to prefer a constructive (full line)rather a destructive (dotted)interference between the two contri-butions,but the tail of the hadronic amplitude does not2 affect at all the Primakoffpeak in the range of small−twhere it dominates.Quantitatively,the hadronic amplitude is the same asin ref.[8],where its detailed expression and an extended discussion on the choice of the vertices and coupling con-stants can be found.Suffice to say that the amplitude is based on the exchange of the Regge trajectories of theρandωmesons,and takes into account the full spin-isospin structure of the electromagnetic and the strong vertices. We have chosen a degenerate Regge propagator for the ω,in order to accommodate for the minimum in the ex-perimental angular distribution around−t=0.5GeV2:Pω=(gµν−kµωkνωs◦αω(t)−1πα′ωΓ(αω(t))×1+exp[−iπαω(t)]m2ρ) s sin[παρ(t)]124m3V m2πg2Vπγ(5)This gives gωπγ=0.314,forΓω→πγ=720keV,and gρπγ=0.103,forΓρ→πγ=68keV[8].It turns out that the contraction between the mass dependent term kµρkνρ/m2ρof the vector meson propaga-tor and the electromagnetic vertex vanishes,and only the contribution of the gµνpart survives.Therefore, the Primakoffamplitude takes the same form as the vec-tor meson exchange amplitudes,provided that the Regge propagator is replaced by the Feynman propagator of the photonPγ=gµν16g2πγγ(7)The full curve in Figure1corresponds to the centralvalueΓπ→γγ=8eV of ref.[7](gπγγ=0.0114),while thedot-dashed curve uses8.4eV at the edge of the experi-mental values.Due to the structure of the electromagnetic vertices,both the hadronic amplitude and the Primakoffampli-tudes strickly vanish atθπ=0,and therefore t min.How-ever,the photon pole is so close to the physical regionthat it boosts the Primakoffamplitude orders of magni-tude above the strong amplitude.b1meson exchange may also contribute to the strongamplitude.In ref.[8]we found that,while it is necessaryto reproduce the beam asymmetry,it only modifies byabout10%the unpolarized cross section in the region ofthe minimum(−t∼0.5GeV2)and above.So it maymodify by the same amount the strong amplitude below−t∼10−3GeV2.Since our knowledge of its couplingconstants is on less solid ground than those ofρandωmesons,I do not retain its contribution.The model confirms the earlier estimate of the crosssection which was included in the experimental pa-pers[9,10].While there is no reason why the Primakoffamplitudes be different,the strong amplitude includedexchanges of theωand b1meson Regge trajectories andtheωPomeron cut,following refs.[11,12].The residuesof the poles werefitted to the data,contrary to the modelwhich I use:in ref.[8]we chose the values of strongand the electromagnetic coupling constants in the rangeof values determined in independent channels,and weimplemented the full spin-isospin structure of the lowermass realization of each Regge trajectory.In Figure1the experimental points have been plottedat the mean value of−t in each experimental bin inθπ◦.A new experimental determination of theπ◦Primakoffcross section,with a better angular resolution,is highlydesirable,especially in the domain where the Primakoffand the strong amplitudes interfere.Increasing the energy up to Eγ=9GeV does notchange dramatically the picture.As it can be seen in Fig-ure2,t min decreases by a factor two,but this does notimprove the separation between the Primakoffand thehadronic peak,which was already very good at5.8GeV.Note that the Regge model reproduces quite well the ex-perimental data[13]at this energy also.On the contrary,increasing the energy helps in theηandη′channels.Figure3shows the angular distributionof theηemitted in the p(γ,η)p reaction at Eγ=6GeV.The value of t min is more than two orders of magnitudebigger than in theπ◦channel.Consequently,one has torely on the tail of the Primakoffamplitude,which shows31010110d σ/d t (µb /Ge V 2)FIG.2:duced in the reaction p (γ,π◦)p ,at E γ=9GeV.The meaning of the curves is the same as in Fig.1.up above the tail of the strong amplitude.The model uses the same ρexchange amplitude (de-generate Regge propagator,eqs.3,with the same strong coupling constants)as in the π◦channel.The radiative coupling constant g ρηγ=0.81is deduced from the ex-perimental decay width Γρ→ηγ=39keV [7]with eq.5(where the πmass is replaced by the ηmass,m η).In the ωexchange amplitude,the radiative decay con-stant g ωηγ=0.29is also fixed by the experimental decay width Γω→ηγ=5.4keV [7].But,following ref.[14],I use the degenerate form,eq.3,instead of the non degen-erate form which I used in the π◦channel.The reason is that available experimental data [15]do not exhibit a minimum in the vicinity of the first node of the ωnon-degenerate Regge trajectory.In nature,Regge trajecto-ries (in the form of eq.1)go by pair,each having the same slope but a different signature,S =±1,when it connects members with either odd or even spins.When it hap-pens that each trajectory has the same,or comparable,coupling constants with the probe,they combine into a degenerate trajectory with or without a rotating phase (eq.3).Only experiment tells us what is the best choice.The conjecture is that the photon couples to a degener-ate trajectory of the ωin the ηphotoproduction channel,while it couples to a non-degenerate ωtrajectory in the π◦sector.Consequently the strong coupling constants of the omega are not necessarily the same in both channels.A good agreement with the data is achieved when I use g 2ωNN /4π=6.44and I keep κω=0.1010101101010101010-t GeV 2d σ/d t (µb /Ge V 2)FIG.3:The angular distribution of the ηmesons photopro-duced in the reaction p (γ,η)p ,at E γ=6GeV.The meaning of the curves is the same as in Fig.1.This set of coupling constants is different from the setof ref.[14]which has been obtained from a global fit in the ηand η′sector.I prefer to use a set which differs in a minimal way from the π◦sector set.It is worth to note that both sets lead to a similar accounting of the strong part of the cross section.The Primakoffcoupling constant of the ηmeson,g ηγγ=0.0429,is deduced from the average (includ-ing Primakoffmeasurement)value Γη→γγ=0.46keV of ref.[7]with the help of eq.7(where the πmeson mass is replaced by the ηmeson mass).The experimental study of the Primakoffeffect will greatly benefit of the increase of the incoming photon energy.Figure 4clearly demonstrates that,at E γ=11GeV,t min is lowered by about a factor three and the Primakoffpeak is clearly separated from the strong hadronic peak.Let us turn now to the η′channel,where I keep the same amplitudes as in the ηchannel and only change the radiative coupling constants.The η′radiative decay to the ρor the ωmesons is related to the radiative coupling constant in the following way:Γη′→V γ=αem (m 2η′−m 2V )3410-310-210-1110-610-510-410-310-210-1-t GeV 2d σ/d t (µb /Ge V 2)p(γ,η)pE γ = 11 GeVRegge ω+ρPrimakoffΓηγγ = 0.46 keVFIG.4:The angular distribution of the ηmesons photopro-duced in the reaction p (γ,η)p ,at E γ=11GeV.The meaning of the curves is the same as in Fig.1.Γη′→γγ=4.27keV of ref.[7]with the help of eq.7(where the πmeson mass is replaced by the η′meson mass).The results are shown in Figure 5at E γ=11GeV.Even at such a high energy,t min is high and the Pri-makoffcontribution appears as a shoulder on the tail of the strong amplitude.The situation is similar as in the ηsector at E γ=6GeV.Certainly an experiment with an excellent energy resolution will disentangle the Primakoffamplitude at the lowest angles,where it overwhelms by more that an order of magnitude the strong amplitude,which will be calibrated at higher angles.A measure-ment of ηmeson production at E γ=6GeV would be very welcome in this respect:it is already possible.Contrary to the π◦and the ηchannels,the experi-mental data set is extremely scarce.The model can only be compared to integrated experimental cross sec-tions [16,17].At E γ=5GeV,it predicts σ=0.1µb in the range of the experimental cross section σexp =0.17±0.12µb.This gives confidence in its extrapolation from the ηto the η′channel.But a more accurate deter-mination of the angular distribution is definitely needed.In conclusion,the Regge description of the strong hadronic amplitude has been extended from π◦to ηand η′photo-production.It reproduces all the available ex-perimental data and provides us with a solid starting point to evaluate the hadronic contribution below the Primakoffpeak.The Primakoffamplitude has been in-corporated in the model.While in the π◦sector it is prominent already at E γ=6GeV,its determination10-310-210-1110-610-510-410-310-210-1-t GeV 2d σ/d t (µb /Ge V 2)p(γ,η,)pE γ = 11 GeVRegge ω+ρPrimakoff Γη,γγ = 4.27 keVFIG.5:The angular

Abstract
At very high energy and wide angles, Compton scattering on the proton (γp → γp) is described by perturbative QCD. The perturbative QCD calculation has been performed several times previously, at leading twist and at leading order in αs , with mutually inconsistent results, even when the same light-cone distribution amplitudes have been employed. We have recalculated the helicity amplitudes for this process, using contour deformations to evaluate the singular integrals over the light-cone momentum fractions. We do not obtain complete agreement with any previous result. Our results are closest to those of the most recent previous computation, differing significantly for just one of the three independent helicity amplitudes, and only for backward scattering angles. We present results for the unpolarized cross section, and for three different polarization asymmetries. We compare the perturbative QCD predictions for these observables with those of the handbag and diquark models. In order to reduce uncertainties associated with αs and the three-quark wave function normalization, we have normalized the Compton cross section using the proton elastic form factor. The theoretical predictions for this ratio are about an order of magnitude below existing experimental data.

1IntroductionExclusive real Compton scattering on the proton, γp → γp, is a promising arena √ for studying the short-distance structure of the proton. In the limit of large energy s and fixed scattering angle θ in the center-of-mass frame, the real Compton amplitude should factorize as the convolution of a perturbative hard scattering matrix element with a nonperturbative light-cone distribution amplitude [1]. The distribution amplitude is for the three valence quarks in the proton; it describes how their longitudinal momentum is partitioned when their transverse separation is very small. Contributions of Fock space states with more partons in the proton’s light-cone wave function should be suppressed by additional powers of s. However, the energy at which this asymptotic prediction of perturbative QCD (PQCD) becomes valid is not known a priori. Soft mechanisms such as the soft overlap (or handbag) model [2, 3, 4] and the diquark model [5, 6] could be comparable to, or even dominant over, the PQCD mechanism at the presently accessible center-of-mass energies of 2–4 GeV. The PQCD prediction for γp → γp contains a number of uncertainties. First, only the Born level has been computed; next-to-leading-order corrections are likely to be large. Related to this, the Born level prediction is proportional to a high power of the running strong coupling constant, [αs (µ)]4 , and its renormalization-scale (µ) dependence leads to a large normalization uncertainty on the cross section. Second, the form of the proton distribution amplitude is not well understood. Several groups have produced model distribution amplitudes based primarily on QCD sum rule analyses [7, 8, 9, 10, 11, 12, 13]. These distribution amplitudes can lead to quite different predictions for the Compton helicity amplitudes. Most of the proposed distribution amplitudes tend to peak in a region where two of the three quarks carry relatively small fractions x of the proton longitudinal momentum. This has led to skepticism about the applicability of PQCD at accessible energies [14, 15, 2, 3], √ because relatively soft sub-processes (relative to s) can reorient quarks with small x from the initial proton direction to the final proton direction. Despite all these caveats, it is still useful to know the PQCD predictions for γp → γp, if nothing else as an asymptotic limit. There have already been four separate calculations at Born level [16, 17, 18, 19]. However, no two results agree with each other, even when the same proton distribution amplitudes are assumed. Given this discrepancy in the literature, and the need for consistent predictions from the PQCD mechanism, we undertook an independent recalculation of this process. Our results in fact differ from all previous work, although we find reasonable agreement with ref. [18] for a subset of the helicity amplitudes, and excellent agreement with ref. [19] for forward scattering angles. Our results are timely in view of the experimental situation. For over twenty years, the highest energy wide-angle Compton data available have been from an experiment at Cornell [20] which investigated the energy range 4.6 GeV2 < s < 12.1 GeV2 . These data appear to obey an approximate dσ/dt ∝ s−6 scaling law, as predicted by PQCD, although more precise data would be useful to confirm or refute this behavior. An experiment now underway at Jefferson Lab [21] should soon improve the errors on the unpolarized cross section and its θ- and s-dependence, in the same kinematic range as the Cornell experiment. This experiment also plans to measure a polarization asymmetry, the transfer of longitudinal
