"Figure 2 (38.8 GeV CH3 covariance)" of "Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation"

Covariance of the data uncertainty contribution to the tuned intrinsic kT parameters between the two generator settings of Herwig at proton-proton center-of-mass energy 38.8 GeV.

在质子-质子质心系能量为38.8 GeV的条件下，Herwig两种发生器组态之间，针对调优后本征kT参数的数据不确定性贡献的协方差。
