论文摘要
CMS和图腾实验的精确质子光谱仪（PPS）收集了107.7 fb $^{ - 1} $在LHC处的质子 - 普罗顿（PP）碰撞中的13 TEV（运行2）。本文介绍了PPS对齐和光学校准的关键特征，质子重建过程以及检测器效率和PPS模拟的性能。使用（半）独家DILEPTON事件样本对重建和仿真进行验证。 PPS的性能证明了在高光度强调强子对撞机上连续操作近光质子光谱仪的可行性。
The Precision Proton Spectrometer (PPS) of the CMS and TOTEM experiments collected 107.7 fb$^{-1}$ in proton-proton (pp) collisions at the LHC at 13 TeV (Run 2). This paper describes the key features of the PPS alignment and optics calibrations, the proton reconstruction procedure, as well as the detector efficiency and the performance of the PPS simulation. The reconstruction and simulation are validated using a sample of (semi)exclusive dilepton events. The performance of PPS has proven the feasibility of continuously operating a near-beam proton spectrometer at a high luminosity hadron collider.
