论文摘要
我描述了一个可能的正向多粒子光谱仪（FMS），可以在运行4中安装超导重组偶极子D1的下游，从z = 96 m -126 m，以测量RT（s）= 14 TEV的低亮度P + P碰撞中的多型TEV HADRON光谱，以及P + O + O + O + O + O + O + O + O + O + O + collisions cosmic cosmic ray ray cormic ray cormic ray。可以测量高Feynman XF处的轻质反核和迷人的Hadron，这对于天体物理学都很重要。在全高亮度HL-LHC上，搜索在20 m长的70 cm直径为70 cm的真空管中衰减的新长寿命中性颗粒（LLP）到可见的衰减模式（包括gamma+gamma+e+e+e+e+e-，mu+mu-，tau+mu-，tau+tau+tau+tau+tau+tau-，ccbar and jets）。 FMS特别适合LLP，具有1 GEV <m（x）<10 GEV和Lifetimes C.Tau的LLP，从约10 m到几公里。 我将其讨论为CMS的可能补充，但尚未正式批准，因此不会代表CMS发表演讲。
I describe a possible Forward Multiparticle Spectrometer (FMS) that could be installed downstream of the superconducting recombination dipole D1 in Run 4, from z = 96 m - 126 m to measure multi-TeV hadron spectra in low luminosity p + p collisions at Rt(s) = 14 TeV, as well as p + O and O + O collisions as relevant for cosmic ray showers. Light antinuclei and charmed hadrons at high Feynman xF can be measured, both of importance for astrophysics. At the full high luminosity HL-LHC a search for new long-lived neutral particles (LLPs) decaying in a 20 m long, 70 cm diameter vacuum pipe to visible decay modes (including gamma+gamma, e+e-, mu+mu-, tau+tau-, ccbar and jets) can be made. The FMS is especially well suited for LLPs with 1 GeV < M(X)< 10 GeV and lifetimes c.tau from about 10 m to several km. I discuss this as a possible addition to CMS but it has no formal approval yet, therefore the talk is not given on behalf of CMS.
