用顶夸克数据探测QCD参数

Probing QCD Parameters with Top-Quark Data

Sebastian Naumann-Emme

摘要:

在质心能量为7和8 TeV的质子-质子碰撞中,对顶夸克产生截面进行了包容性和差分测量,并将测量结果与微扰量子色动力学中次领先和次领先次领先阶的预测结果进行了比较。从这些研究中,顶夸克的质量,强耦合常数,并对部分子分布函数的约束被确定。

英文摘要:

Results from inclusive and differential measurements of the production cross sections for top quarks in proton-proton collisions at center-of-mass energies of 7 and 8 TeV are compared to predictions at next-to-leading and next-to-next-to-leading order in perturbative Quantum Chromodynamics. From these studies, constraints on the top-quark mass, the strong coupling constant, and on parton distributions functions are determined.
