Abstract

An algorithm has been developed for reconstructing long-lived particles (LLP) decaying in the barrel and endcap regions of the muon system of the CMS detector at the Large Hadron Collider. Calculations were done on the basis of Monte Carlo simulated data using CMSSW package, adapted to the conditions of CMS detector experimental setup of 2018. In considered process the hypothetical LLP particles are produced from decays of B mesons in proton–proton (p–p) collisions at a center-of-mass energy of 13 TeV. Decays of LLP particles in the muon system of the CMS detector are characterized by the presence of wide showers with a large multiplicity of hits from the muon chamber channels, which differs significantly from the hits of known particles, and is a good criterion for identifying LLP particles.

长寿命粒子在CMS (LHC)实验中的重构
提出了一种重构长寿命粒子(LLP)的算法,该算法在大型强子对撞机CMS探测器的介子系统的桶区和端区衰变。根据2018年CMS探测器实验设置条件,利用CMSSW软件包对蒙特卡罗模拟数据进行计算。在考虑的过程中,假设的LLP粒子是由质子-质子(p-p)碰撞中B介子的衰变产生的,质心能量为13 TeV。在CMS探测器的μ介子系统中,LLP粒子的衰变以μ介子腔通道的大量撞击为特征,这与已知粒子的撞击有很大的不同,这是识别LLP粒子的一个很好的标准。
