核子弹性散射的现代模型及其对LHC的预言

Contemporary models of elastic nucleon scattering and their predictions for LHC

Jan Kaspar, Vojtech Kundrat, Milos Lokajicek

摘要:

带电核子的弹性碰撞的分析是建立在West和Yennie公式的基础上的。然而,这种方法最近已被证明是不够的,从实验以及理论的观点。程函模型似乎更相关,因为它能够确定碰撞参量空间的物理特性。当然,当代的唯象模型不能给出任何明确的答案,因为弹性碰撞可以被不同地解释为中心过程或外围过程。然而,在此基础上给出了计划中的LHC能量的预测,并考虑了精确测定光度的可能性。

英文摘要:

The analyses of elastic collisions of charged nucleons have been based standardly on West and Yennie formula. However, this approach has been shown recently to be inadequate from experimental as well as theoretical points of view. The eikonal model seems to be more pertinent as it enables to determine physical characteristics in impact parameter space. The contemporary phenomenological models cannot give, of course, any definite answer as the elastic collisions may be interpreted differently, as central or peripheral processes. Nevertheless, the predictions for the planned LHC energy have been given on their basis and the possibility of exact determination of luminosity has been considered.
