高能核子-核子弹性衍射和质子上矢量介子的完全衍射电产生的一个简单模型

A simple model for high-energy nucleon-nucleon elastic diffraction and exclusive diffractive electroproduction of vector mesons on protons

A. A. Godizov

摘要:

在一个统一的Regge程函模型的框架下,考虑了高能下$p+p\to p+p$、$\bar p+p\to\bar p+p$和$γ^*+p\to V+p$的衍射排斥散射过程.结果表明,坡密子轨道在所有反应中都具有普适性,其截距约为1.31,这可以从质子结构函数$F_2(x,Q^2)$的数据中得到明确的解释.给出了LHC能区质子-质子截面的预言。

英文摘要:

The processes of exclusive diffractive scattering $p+p\to p+p$, $\bar p+p\to\bar p+p$, and $γ^*+p\to V+p$ at high energies are considered in the framework of a unified Regge-eikonal model with a very simple reggeon structure of the eikonal. It is demonstrated that the pomeron trajectory is universal in all reactions and having intercept about 1.31 which could be exctracted explicitly from the data on the proton structure function $F_2(x,Q^2)$. The predictions for the proton-proton cross-sections at LHC energies are given.
