Abstract

The values of the parameters $ρ^{p p}, σ_{tot}^{p p}$ and $B^{p p}$ extracted in the region of Coulomb-nuclear interference (CNI) in the ATLAS and TOTEM experiments at energy $\sqrt{s} = 13$ TeV are studied based on the general expression for the Coulomb-nuclear amplitude. Due to the significant differences between these data, we undertake both their joint analysis and the retrieval of parameter values separately for each experiment. A significant incompatibility of these parameters published by the ATLAS and TOTEM experiments is shown. This is especially noticeable in the case of $σ_{tot}$ and the situation is similar to what once happened at the TEVATRON: the values of $σ_{tot}^{A T L A S}$ with account of errors do not overlap with $σ_{tot}^{T O T E M}$ .

图腾与天神的歧义:人们不应该担心吗?

根据库仑-核振幅的一般表达式，研究了能量s=13 TeV时ATLAS和TOTEM实验中库仑-核干涉(CNI)区域中提取的参数ρpp、σtotpp和Bpp的取值。由于这些数据之间存在显著差异，我们对每个实验分别进行联合分析和参数值检索。这些参数在ATLAS和TOTEM实验中有明显的不相容。这在σ totot的情况下尤其明显，情况类似于曾经发生在TEVATRON的情况:考虑误差的σtotATLAS的值与σ tototem的值不重叠。
