论文摘要
在本文中，我们详细介绍了光（lbl），达勒姆（LBL），达勒姆和双衍射过程的副作用，用于超疗法$ pbpb $ collisisions在大型强子碰撞器（LHC），高 - 能量LHC（HE -LHC）和未来的圆形碰撞器（FCC）。考虑了中央和正向LHC检测器的接受，并提出了不变质量，速度，横向动量和链球分布的预测。我们的结果表明，Durham和双衍射过程的贡献可以通过排他性削减来强烈抑制，这将允许对LBL散射进行精确的分析，以及在最终状态下对超出标准模型物理的搜索。
In this paper we present a detailed analysis of the contribution of the Light -- by -- Light (LbL), Durham and double diffractive processes for the diphoton production in ultraperipheral $PbPb$ collisions at the Large Hadron Collider (LHC), High -- Energy LHC (HE -- LHC) and Future Circular Collider (FCC). The acceptance of the central and forward LHC detectors is taken into account and predictions for the invariant mass, rapidity, transverse momentum and acoplanarity distributions are presented. Our results indicate that the contribution of the Durham and double diffractive processes can be strongly suppressed by the exclusivity cuts, which will allow to perform a precise analysis of the LbL scattering, as well the search of beyond Standard Model physics in this final state.
