AI 中文摘要
基于弹性质子-质子($pp$)以及可能的质子-反质子($p\bar{p}$)截面的几何标度,我们依据两个相互作用半径$R(s)$和$Q(s)$分别推导出了关于复交叉偶和交叉奇散射振幅的简单公式。采用总截面的COMPETE参数化,我们高精度地重现了$\rho^{pp}$和$\rho^{p\bar{p}}$参数,但未涵盖13 TeV时TOTEM和ATLAS的数据点。我们表明,对与奥德龙对应的$p\bar{p}$总截面进行轻微修正,能够纳入$\rho^{pp}$ 13 TeV的数据。
英文摘要
Based on geometric scaling of elastic $pp$ and possibly $p\bar{p}$ cross-sections, we derive simple formulae for the complex crossing-even and crossing-odd scattering amplitudes in terms of two interaction radii: $R(s)$ and $Q(s)$, respectively. Employing the COMPETE parametrization of the total cross-sections, we reproduce $ρ^{pp}$ and $ρ^{p\bar{p}}$ parameters with high accuracy, however we miss the 13~TeV TOTEM and ATLAS points. We show that a slight modification of the $p\bar{p}$ total cross-section corresponding to the Odderon, allows to accommodate $ρ^{pp}$ 13~TeV data.
