13 TeV与ALICE pp碰撞中带电粒子喷流产生的多重数依赖性

Multiplicity dependence of charged-particle jet production in pp collisions at 13 TeV with ALICE

Debjani Banerjee

摘要:

pp碰撞中喷流产生和喷流性质的测量提供了微扰量子色动力学(pQCD)的测试,并形成了重离子(A-A)碰撞中类似测量的基线。在这方面的贡献,我们报告最近的ALICE测量带电粒子喷流生产和喷流内的属性,包括平均带电成分的多重性和碎片分布领先的喷气机,在最小偏差PP碰撞在$\sqrt{s} = 13\,$ TeV。此外,事件的多重性依赖于喷流的产生和喷流的性质在pp碰撞在$\sqrt{s} = 13\,$ TeV将被提出。将结果与理论模型预测进行比较。

英文摘要:

Measurements of jet production and jet properties in pp collisions provide a test of perturbative quantum chromodynamics (pQCD) and form a baseline for similar measurements in heavy ion (A--A) collisions. In this contribution, we report recent ALICE measurements of charged-particle jet production and intra-jet properties, including mean charged-constituent multiplicity and fragmentation distribution for leading jets, in minimum bias pp collisions at $\sqrt{s} = 13\,$TeV. In addition, the event multiplicity dependence of jet production and jet properties in pp collisions at $\sqrt{s} = 13\,$TeV will be presented. Results will be compared with theoretical model predictions.
