JETSCAPE框架是一个用于模拟高能核碰撞的模块化多功能蒙特卡罗软件包。在这项工作中，我们提出了一个新的调整JETSCAPE，称为PP 19，并验证它的比较，以喷射为基础的测量在$p+p$碰撞，包括包容性的单喷流截面，射流形状可观，碎裂功能，带电强子截面，和双喷流质量截面。这些在p+p碰撞中的可观测量为它们在核碰撞中的对应物提供了基线。因此，量化的JETSCAPE结果与$p+p$数据的协议水平是必要的有意义的应用JETSCAPE的A+A碰撞。计算使用本文中定义的JETSCAPE PP 19调，基于JETSCAPE框架的1.0版本。对于在这项工作中讨论的可观的计算使用JETSCAPE PP 19同意在一个相当于标准蒙特卡罗代码的水平在很宽的碰撞能量范围内的数据。这些结果证明了JETSCAPE框架的物理能力，并为JETSCAPE用户提供基准。
The JETSCAPE framework is a modular and versatile Monte Carlo software package for the simulation of high energy nuclear collisions. In this work we present a new tune of JETSCAPE, called PP19, and validate it by comparison to jet-based measurements in $p+p$ collisions, including inclusive single jet cross sections, jet shape observables, fragmentation functions, charged hadron cross sections, and dijet mass cross sections. These observables in $p+p$ collisions provide the baseline for their counterparts in nuclear collisions. Quantifying the level of agreement of JETSCAPE results with $p+p$ data is thus necessary for meaningful applications of JETSCAPE to A+A collisions. The calculations use the JETSCAPE PP19 tune, defined in this paper, based on version 1.0 of the JETSCAPE framework. For the observables discussed in this work calculations using JETSCAPE PP19 agree with data over a wide range of collision energies at a level comparable to standard Monte Carlo codes. These results demonstrate the physics capabilities of the JETSCAPE framework and provide benchmarks for JETSCAPE users.
