高能质子-核碰撞中的μ子多重数

Muon multiplicity at high energy proton-nuclei collisions

E. A. Kuraev, S. Bakmaev, V. Bytev, E. Kokoulina

摘要:

本文给出了高能质子-核碰撞产生μ介子和π介子多重数的估计。考虑了QED和QCD对μ子对和$σ$ -介子产生的外围运动学的贡献,并考虑了它最终转化为μ子。试图解释宇宙介子簇射中带正电的介子相对于带负电的介子的过剩。我们推导出$n$对的截面随$n$的变化关系,在大n时为$d^n(n!n^2)^{-1}$。

英文摘要:

Estimation of multiplicity of muons and pions production at high energy proton-nuclei collisions is given. Both QED and QCD contributions are considered for peripheral kinematics of muon pair and $σ$-meson production, keeping in mind it's final conversion to muons. An attempt to explain the excess of positive charged muons compared to negative one in cosmic muon showers is given. We derive the dependence of cross-section of $n$ pairs as a function of $n$ at large n as $d^n(n!n^2)^{-1}$.
