Measurement of the associated production of a Z boson and bottom or charm quarks with the ATLAS experiment

将在欧洲核子研究中心的大型强子对撞机的ATLAS实验中测量质子-质子碰撞中产生Z玻色子与一个或两个B或c夸克的包容截面和微分截面。测量将基于ATLAS探测器在2015-2018年期间收集的质子碰撞数据，质心能量为13 TeV。测得的横截面将比较国家的最先进的模拟和计算在最高的可用阶微扰QCD，使用各种味道和质量计划和几个部分分布函数与不同的描述的底部和魅力的质子内容。

A measurement will be performed of the inclusive and differential cross section of the production of a Z boson in association with one or two b or c quarks in proton-proton collisions at the ATLAS experiment at the Large Hadron Collider at CERN. The measurement will be based on proton collision data collected with the ATLAS detector during 2015-2018 at a center-of-mass energy of 13TeV. The measured cross sections will be compared to state-of-the-art simulations and calculations at highest available order in perturbative QCD, using various flavour and mass schemes and several Parton Distribution Functions with different descriptions of the bottom and charm content of the proton.
