论文摘要
在本文中，我们在模型[19]中讨论了Odderon的贡献，该贡献提供了$σ_{\ rm tot} $ $ $σ_{\ rm el} $和$ b _ {\ rm el} $的相当好的描述。我们表明，阴影校正很大，并且对Odderon贡献的能量有很大的依赖性，而在扰动QCD中，这不取决于能量。这种能量依赖性与$ρ= {\ rm re}/{\ rm im} $的实验数据一致，假设Odderon在W = 7 TEV时给出了约1 Mb的贡献。这与我们对基于CGC的模型的估计有很大不同。我们重现了通过实验测量的$ t $依赖性的主要特征：弹性横截面的斜率小$ t $，Minima在$ t $ - 依赖性中的存在，位于$ | t | _ {min {min} $ = 0.52 Gev 2 gev 2 in w = 7 tev = 7 tev;以及弹性横截面的行为$ | t | > | t | _ {min} $。弹性振幅的实际部分比实验振幅小得多。因此，为了实现数据描述，有必要添加Odderon贡献。
In this paper we discuss the Odderon contribution in our model[19] that gives a fairly good description of $σ_{\rm tot}$ $σ_{\rm el}$and $B_{\rm el}$ for proton-proton scattering. We show that the shadowing corrections are large, and induce considerable dependence on energy for the Odderon contribution, which in perturbative QCD does not depend on energy. This energy dependence is in agreement with the experimental data for $ρ= {\rm Re}/{\rm Im}$, assuming that the Odderon gives a contribution of about 1 mb at W = 7 TeV. This differs greatly with our estimates for a CGC based model. We reproduce the main features of the $ t$ -dependence that are measured experimentally: the slope of the elastic cross section at small $t$, the existence of the minima in $t$-dependence which is located at $|t|_{min}$ = 0.52 GeV 2 at W= 7 TeV; and the behaviour of the elastic cross section at $ |t| > |t|_{min}$.The real part of the elastic amplitude turns out to be much smaller than the experimental one. Consequently, to achieve a description of the data, it is necessary to add an odderon contribution.
