LHC上固定靶碰撞中矢量介子的光生

Exclusive vector meson photoproduction in fixed - target collisions at the LHC

V. P. Goncalves, M. M. Jaime

摘要:

研究了LHC固定靶碰撞中$ρ$、$ω$和$J/Ψ$的光生排他过程.本文首次用STARlight Monte Carlo方法计算了LHC上$p He$、$p Ar$、$Pb He$和$Pb Ar$固定靶碰撞中矢量介子光生的快度和横动量分布,并给出了总截面的计算结果。预测的运动范围探测LHCb探测器也提出。我们的结果表明,在LHC的固定靶碰撞中对这一过程进行实验分析是可行的。这种未来的分析将探讨QCD动力学在运动学范围内的补充研究对撞机模式。

英文摘要:

The exclusive $ρ$, $ω$ and $J/Ψ$ photoproduction in fixed - target collisions at the LHC is investigated. We estimate, for the first time, the rapidity and transverse momentum distributions of the vector meson photoproduction in $p He$, $p Ar$, $Pb He$ and $Pb Ar$ fixed - target collisions at the LHC using the STARlight Monte Carlo and present our results for the total cross sections. Predictions for the kinematical range probed by the LHCb detector are also presented. Our results indicate that the experimental analysis of this process in fixed - target collisions at the LHC is feasible. Such future analysis will probe the QCD dynamics in a kinematical range complementary to that studied in the collider mode.
