用ALICE研究pp和p-Pb中的软QCD物理

Soft-QCD physics in pp and p-Pb with ALICE

Valentina Zaccolo

摘要:

在LHC达到的高碰撞能量下,硬过程的贡献越来越大,这可以用微扰QCD计算。尽管如此,粒子产生仍然以软QCD为主,转移动量为几个GeV。这些现象用非微扰唯象学来描述,并对理论模型提出了挑战。ALICE已经测量了几个针对软QCD的可观测量,无论是在运行1和2质子-质子和质子-铅碰撞在LHC。一个选择的结果将在这些程序中,重点放在模型的比较和总结了近8年的数据采集后的软QCD的理解。

英文摘要:

At high collision energies as achieved at the LHC there are increasing contributions from hard processes, which can be computed with perturbative QCD. Nevertheless, particle production is still dominated by soft QCD with transferred momentum of a few GeV. These phenomena are described by non-perturbative phenomenology and challenge the theoretical models. ALICE has measured several observables which target soft QCD, both in Run 1 and 2 proton-proton and proton-lead collisions at the LHC. A selection of results will be presented in these proceedings, focusing on the model comparisons and summarising the understanding of soft QCD after almost 8 years of data taking.
