Pythia 8 Monte Carlo事件generator中pT0参数的能量依赖性研究

Investigation of the energy dependence of the pT0 parameter in the Pythia 8 Monte Carlo event generator

Paolo Gunnellini, Hannes Jung, Rachalis Maharucksit

摘要:

通过使用Pythia 8 Monte Carlo事件发生器的预测,我们确定了模拟多部分子相互作用的部分子截面的能量依赖的翻转值(pT 0)。由于观测到的pT 0值的能量依赖性不能很好地用幂律函数描述,我们引入了一个额外的能量依赖项,以更好地描述能量范围sqrt(s)= 0.3-13 TeV的实验观测。我们获得了类似的协议水平的预测使用不同的部分子密度。

英文摘要:

By using predictions from the Pythia 8 Monte Carlo event generator, we determine the energy-dependent turn-over values (pT0) of the partonic cross section for the simulation of multiparton interactions. Since the observed energy dependence of the pT0 values is not well described by a power-law function, we introduce an additional energy-dependent term, to better describe the experimental observations in the energy range sqrt(s) = 0.3-13 TeV. We obtain a similar level of agreement for predictions using various parton densities.
