超高能强子衍射散射和库仑相互作用
Hadron diffractive scattering at ultrahigh energies and coulomb interaction
摘要：
在先前确定振幅实部的基础上，我们研究了强子和库仑相互作用对LHC能区$pp$散射的影响[{ \it V. V. Anisovich，V.A. Nikonov，J. Nyiri}，Int.J.Mod.Phys.A { \bf 30}，1550188（2015）]。本文用$K$矩阵函数方法讨论了强子与库仑相互作用的干涉。在强子渐近相互作用的黑盘模型下，我们计算了能量一直到$\sqrt{s}= 10^6$ TeV的强子干涉效应.结果表明，振幅的实部集中在黑盘边界处的碰撞参量空间中，导致相互作用效应随着能量的增加而增加。
英文摘要：
We study the interplay of hadronic and Coulomb interactions for $pp$ scattering at LHC energies on the basis of the previous determination of the real part of the amplitude [{\it V.V. Anisovich, V.A. Nikonov, J. Nyiri}, Int. J. Mod. Phys. A{\bf 30}, 1550188 (2015)]. The interference of hadron and Coulomb interactions is discussed in terms of the $K$-matrix function technique. Supposing the black disk mode for the asymptotic interaction of hadrons, we calculate interference effects for the energies right up to $\sqrt{s}= 10^6$ TeV. It turns out that the real part of the amplitude is concentrated in the impact parameter space at the border of the black disk that results in a growth of interplay effects with the energy increase.
