QCD喷流的标度模式

Scaling Patterns for QCD Jets

Erik Gerwick, Tilman Plehn, Steffen Schumann, Peter Schichtel

摘要:

强子对撞机的喷流发射遵循简单的标度模式。基于微扰QCD,我们导出了终态和初态辐射的泊松标度和阶梯标度。部分子密度效应在低多重数下增强阶梯标度。我们提出了我们的理论研究结果在Z+喷流和QCD间隙喷流生产的基础上,对目前的LHC分析轻微增加的实验测试。

英文摘要:

Jet emission at hadron colliders follows simple scaling patterns. Based on perturbative QCD we derive Poisson and staircase scaling for final state as well as initial state radiation. Parton density effects enhance staircase scaling at low multiplicities. We propose experimental tests of our theoretical findings in Z+jets and QCD gap jets production based on minor additions to current LHC analyses.
