论文摘要
考虑到LHC的超疗法$ pbpb $碰撞的衍射和独家过程的DILEPTON生产。 $ e^+ e^ - $，$μ^+μ^ - $和$τ^+τ^ - $交叉部分被提出，考虑到在未来的实验分析中可以通过LHCB协作实现的逼真削减。我们的结果表明，与衍射生产相关的背景可以得到很大的抑制，并且可以清晰地分离独家过程。对于$τ^+τ^ - $生产，考虑了半衰变通道。我们的结果表明，对LHCB的DILEPTON生产的未来实验分析是可行的，对于搜索BSM物理学可能很有用。
The dilepton production in diffractive and exclusive processes at forward rapidities considering ultraperipheral $PbPb$ collisions at the LHC is investigated. Predictions for the $e^+ e^-$, $μ^+ μ^-$ and $τ^+ τ^-$ cross sections are presented taking into account of realistic cuts that can be implemented by the LHCb Collaboration in a future experimental analysis. Our results indicate that the background associated with the diffractive production can be strongly suppressed and the exclusive processes can be cleanly separated. For the $τ^+ τ^-$ production, the semi and purely leptonic decay channels are considered. Our results indicate that a future experimental analysis of the dilepton production at the LHCb is feasible and can be useful to search for BSM physics.
