LHC弹性、非弹性和全截面中的Pomeron和Odderon

The Pomeron and Odderon in elastic, inelastic and total cross sections at the LHC

L. Jenkovszky, A. Lengyel, D. Lontkovskyi

摘要:

本文用一个简单的强子弹性衍射散射模型,再现了倾斜-凸起结构,分析了PP和$\bar PP$散射。主要强调的是在倾斜凸块区域,附近的t=-1 GeV $^2$的微妙和非平凡的动力学。该模型的简单性和吸收校正的预期小度使得能够控制对散射振幅的各种贡献,特别是振幅的C-偶分量和C-奇分量之间的相互作用,以及它们的相对贡献,随s和t而变化。的Regge轨迹的非线性的作用进行审查。计算了正向振幅的实部与虚部之比、弹性截面与总截面之比以及非弹性截面。预测的大型强子对撞机的能量区域,大多数现有的模型将被确认或排除,提出。

英文摘要:

A simple model for elastic diffractive hadron scattering, reproducing the dip-bump structure is used to analyze PP and $\bar PP$ scattering. The main emphasis is on the delicate and non-trivial dynamics in the dip-bump region, near t=-1 GeV$^2$. The simplicity of the model and the expected smallness of the absorption corrections enables one the control of various contributions to the scattering amplitude, in particular the interplay between the C-even and C-odd components of the amplitude, as well as their relative contribution, changing with s and t. The role of the non-linearity of the Regge trajectories is scrutinized. The ratio of the real to imaginary parts of the forward amplitude, the ratio of elastic to total cross sections and the inelastic cross section are calculated. Predictions for the LHC energy region, where most of the exiting models will be either confirmed or ruled out, are presented.
