本文详细分析了LHC中13 TeV pp弹性散射前向区微分截面的测量结果。研究了散射振幅的实部和虚部的结构,它们都需要指数因子和线性因子。在不同条件下的数据表示进行了比较,占从色散关系的预测和调查的库仑核干扰的作用。用核程函相位和库仑程函相位的可加性来确定pp散射中的干涉相位,并与相位为零的假设作了比较。研究了这两种假设下的散射振幅实部的结构,并与从数据中提取的信息进行了直接比较。治疗干扰相的替代标准导致$ρ$参数在0.1和0.13之间的不同值,而$σ$相差0.18 MB,并且表明可用的数据不能区分这两种模型。
英文摘要:
Detailed analysis of the measurements of differential cross sections in the forward region of pp elastic scattering at 13 TeV in LHC is performed. The structures of the real and imaginary parts of the scattering amplitude are investigated, both requiring exponential and linear factors. Representations of the data in different conditions are compared, accounting for predictions from dispersion relations and investigating the role of the Coulomb-nuclear interference. The additivity of nuclear and Coulomb eikonal phases to determine the interference phase in pp scattering is submitted to a comparison with assumption of phase equal to zero. The structures of the real part of the scattering amplitude under the two assumptions are examined, and direct comparison is performed with the information extracted from the data. The alternative criteria for the treatment of the interference phase lead to different values for the $ρ$ parameter between 0.1 and 0.13 while $σ$ differ by 0.18 mb, and it is shown that the available data cannot discriminate the two models.
