对数Regge极点

Logarithmic Regge Pole

S. D. Campos

摘要:

本文介绍了对数Regge极点方法中的减法过程和Regge截。减法机制导致与先前在非减法情况下获得的相同的渐近行为。另一方面,Regge割则对总截面的渐近行为的非主导贡献引入了明确的作用。从这些结果中,我们引入了一些简单的参数化方法来拟合质子-质子和反质子-质子总截面的实验数据。得到的拟合参数被用来提出预测的$ρ(s)$参数以及弹性斜率$B(s)$在高能量。

英文摘要:

This work presents the subtraction procedure and the Regge cut in the logarithmic Regge pole approach. The subtraction mechanism leads to the same asymptotic behavior as previously obtained in the non-subtraction case. The Regge cut, on the other hand, introduces a clear role to the non-leading contributions for the asymptotic behavior of the total cross section. From these results, one introduces some simple parameterization to fit the experimental data for the proton-proton and antiproton-proton total cross section above some minimum value up to the cosmic-ray. The fit parameters obtained are used to present predictions for the $ρ(s)$-parameter as well as to the elastic slope $B(s)$ at high energies.
