$p p \to p X p$反应中$η$ '和$η_c$的衍射双弹性产生

Diffractive Double-Elastic Production of $η$' and $η_c$ in the $p p \to p X p$ Reaction

Antoni Szczurek

摘要:

本文在未积分胶子分布函数(UGDF)的形式下讨论了在$pp \to p X p$反应中$η'$和$η_c$介子的双衍射(双弹性)产生。估计了$γ^* γ^* \to η'$融合的贡献。计算并讨论了Feynman $x_F$(或快度)中的分布、质子转移四动量平方($t_1$,$t_2$)和质子出射方位角差($Φ$)。并将计算结果与WA102资料进行了比较。在更高的能量的预测。

英文摘要:

I discuss double-diffractive (double-elastic) production of the $η'$ and $η_c$ mesons in the $pp \to p X p$ reaction within the formalism of unintegrated gluon distribution functions (UGDF). The contribution of $γ^* γ^* \to η'$ fusion is estimated. The distributions in the Feynman $x_F$ (or rapidity), transferred four-momenta squared between initial and final protons ($t_1$, $t_2$) and azimuthal angle difference between outgoing protons ($Φ$) are calculated and discussed. The results are compared with the WA102 data. Predictions at higher energies are presented.
