摘要:

在有效Regge作用量框架中,构造了描述两个Regge化胶子到一个、两个和三个普通胶子的转换的顶点。自洽性:玻色对称性和规范不变性检查被证明是履行。其中最简单的一个是产生一个胶子,它决定了已知的BFKL方程的核心,因此在实验和理论处理程序中得到了深入的验证。本文讨论了用两个实胶子的产生来检验顶点的可能性,这在高能周边核子碰撞的标量介子产生过程中可以显现出来。我们表明,其中包括在相同的有效顶点贡献的两个胶子的发射机制占主导地位相比,一个与创建两个单独的胶子。对LHC装置中荷电π介子对产生截面的数值估计给出了$10 mb$的值或阶。此外,我们估计宇宙射线质子与大气气体核碰撞产生的带正电荷的μ介子(作为π介子的衰变)的过量产生与现代数据合理一致。

英文摘要:

In frames of effective Regge action the vertices describing conversion of two reggeized gluons to one two and three ordinary gluons was constructed. The self-consistency: Bose symmetry and gauge invariance properties checks was shown to be fulfilled. The simplest one with creation of a single gluon was intensively verified in programs of experimental and theoretical treatment since it determine the kernel of of the known BFKL equation. Here we discuss the possibility to check the vertex with creation of two real gluons, which can reveal itself in process of scalar mesons production in high energy peripheral nucleons collisions. We show that the mechanisms which include emission of two gluons in the same effective vertex contribution dominate compared with one with the creation of two separate gluons. Numerical estimations of cross section of pair of charged pions production for LHC facility give the value or order $10 mb$. As well we estimate the excess of production of positively charged muons (as a decay of pions) created by cosmic ray proton collisions with the atmosphere gas nuclei to be in a reasonable agreement with modern data.
