在大型强子对撞机和未来圆形对撞机超周边$PbPb$碰撞中相关的$ϕ$和$J/Ψ$光生

摘要:

本文通过对大型强子对撞机(LHC)和未来圆形对撞机(FCC)能量的双散射机制,分析了超周边$PbPb$碰撞中伴随的$ϕ$和$J/Ψ$光生.我们的研究结果补充了以前的$ρρ$,$J/ΨJ/Ψ$和$ρJ/Ψ$生产的分析。考虑到ALICE和LHCb探测器所覆盖的快度范围,我们给出了对总截面和快度分布的预测,这表明未来对$ϕJ/Ψ$末态的实验分析是可行的.这些结果表明,对重离子碰撞中双矢量介子光生的研究有助于约束双散射机制,提高对高能QCD动力学的理解。

英文摘要:

In this paper we analyze the associated $ϕ$ and $J/Ψ$ photoproduction in ultraperipheral $PbPb$ collisions through the double scattering mechanism for the energies of the Large Hadron Collider (LHC) and Future Circular Collider (FCC). Our results complement a previous analysis for the $ρρ$, $J/ΨJ/Ψ$ and $ρJ/Ψ$ production. We present our predictions for the total cross sections and rapidity distributions considering the rapidity ranges covered by the ALICE and LHCb detectors, which indicate that a future experimental analysis of $ϕJ/Ψ$ final state is feasible. These results point out that the study of the double vector meson photoproduction in heavy ion collisions can be useful to constrain the double scattering mechanism and improve our understanding of the QCD dynamics at high energies.
