JETSCAPE framework:p+presults
Physical Review C ( IF 3.2 ) Pub Date : 
A. Kumar et al.

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.

JETSCAPE框架:p +结果

JETSCAPE框架是用于模拟高能核碰撞的模块化多功能通用蒙特卡洛软件包。在这项工作中,我们提出了一种称为PP19的JETSCAPE新曲调,并通过与p+p碰撞,包括包含在内的单个射流横截面,可观察到的射流形​​状,碎裂函数,带电强子横截面和双射流质量横截面。这些可观察到的p+p碰撞为核碰撞中的对应物提供了基线。量化与JETSCAPE结果的一致程度p+p因此,数据对于将JETSCAPE有意义地应用于A + A碰撞是必需的。计算使用基于JETSCAPE框架1.0版的本文定义的JETSCAPE PP19调谐。对于本工作中讨论的可观察物,使用JETSCAPE PP19进行的计算与在广泛的碰撞能量范围内的数据(与标准蒙特卡洛代码可比)相当。这些结果证明了JETSCAPE框架的物理功能,并为JETSCAPE用户提供了基准。
