Abstract

The underlying event in a proton-proton collision consists of multiple-parton interactions and beam remnants, which typically involve low energy scales. The modeling of these aspects of a collision is not always calculable in perturbative quantum chromodynamics, and is governed by phenomenological parameters that need to be "tuned" to observed data. The results of such an underlying-event tuning performed by the CMS experiment for the Pythia 8 and Herwig 7 generators are presented. Various assumptions in the proton parton distribution functions and parton shower development are tested. The derived tunes are validated using data of a wide range of physics processes, and provide a good description of CMS data at a center-of-mass energy √ s = 13 TeV.
CMS中的蒙特卡罗建模与调优
质子-质子碰撞中的潜在事件由多部分子相互作用和光束残余组成,通常涉及低能尺度。在微扰量子色动力学中,碰撞的这些方面的建模并不总是可计算的,并且由需要“调整”到观测数据的现象学参数控制。本文给出了CMS实验对Pythia 8和Herwig 7生成器执行的这种底层事件调优的结果。对质子部分子分布函数和部分子簇发展的各种假设进行了检验。推导出的音调用广泛的物理过程数据进行了验证,并很好地描述了质心能量√s = 13 TeV的CMS数据。
