ATLAS中7 TeV pp碰撞中孤立瞬发光子的测量

Measurements of isolated prompt photons in pp collisions at 7 TeV in ATLAS

Giovanni Marchiori

摘要:

本文介绍了最近两次在质心能量sqrt(s)= 7TeV的pp碰撞中孤立瞬发光子的包容性产生的截面测量结果。这些结果是基于2010年在大型强子对撞机上使用ATLAS探测器收集的数据。测量覆盖了赝快度范围|η(γ)|<1.37和1.52| η(γ)|<2.37和横向能量范围15 < ET(γ)< 400 GeV。测量的截面进行比较,预测从次到领导阶微扰QCD计算。

英文摘要:

Two recent measurements of the cross section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy sqrt(s) = 7 TeV are presented. The results are based on data collected in 2010 with the ATLAS detector at the Large Hadron Collider. The measurements cover the pseudorapidity ranges |eta(gamma)|<1.37 and 1.52<|eta(gamma)|<2.37 and the transverse energy range 15 < ET(gamma) < 400 GeV. The measured cross sections are compared to predictions from next-to-leading-order perturbative QCD calculations.
