高能弹性核子碰撞理论

To the theory of high-energy elastic nucleon collisions

Vojtech Kundrat, Jan Kaspar, Milos Lokajicek

摘要:

通常使用的West和Yennie积分公式库仑和弹性强子振幅之间的相对相位要求弹性强子振幅的相位在所有运动学允许的t值下保持恒定。基于程函模型方法的更一般的干涉公式没有表现出这种限制。相应的差异将被证明和一些不同的唯象模型的弹性PP散射在14 TeV的能量在LHC的预测将被给出。特别注意由弹性散射数据测定光度,结果表明,如果用West和Yennie公式由干涉区中心的值求出光度,其系统误差可达5%。

英文摘要:

The commonly used West and Yennie integral formula for the relative phase between the Coulomb and elastic hadronic amplitudes requires for the phase of the elastic hadronic amplitude to be constant at all kinematically allowed values of t. More general interference formula based on the eikonal model approach does not exhibit such limitation. The corresponding differences will be demonstrated and some predictions of different phenomenological models for elastic pp scattering at energy of 14 TeV at the LHC will be given. Special attention will be devoted to determination of luminosity from elastic scattering data; it will be shown that the systematic error might reach till 5 % if the luminosity is derived from the values in the center of the interference region with the help of West and Yennie formula.
