来自ATLAS和CMS的软QCD

Soft QCD from ATLAS and CMS

Romain Rougny

摘要:

本文介绍了用ATLAS和CMS实验测量pp碰撞中强子产生的结果,包括在sqrt(s)= 0.9,2.36和7 TeV下,NSD和非弹性事件的带电粒子横动量、赝快度和事件多重数分布。衍射研究与衍射富集或抑制数据样本。总的非弹性截面以及间隙截面测量显示。测量光谱的确定奇怪的强子,重建的基础上,他们的衰变拓扑结构,也进行了讨论。比较几个QCD蒙特卡罗模型和曲调展出。给出了pp碰撞中赝快度和方位角在较宽范围内的两粒子角关联的结果。潜在的事件活动研究与不同的硬探针:轨道,trackjets,热量计集群,或在Drell-Yan事件。

英文摘要:

Measurements of hadron production in pp collisions by the ATLAS and CMS experiments are presented, including charged particle transverse momentum, pseudorapidity and event-by-event multiplicity distributions at sqrt(s) = 0.9, 2.36 and 7 TeV, for NSD and inelastic events. Diffraction is studied with either diffraction enriched or suppressed data samples. Total inelastic cross-section as well as gap cross-section measurements are shown. Measured spectra of identified strange hadrons, reconstructed based on their decay topology, are also discussed. Comparisons to several QCD Monte Carlo models and tunes are exhibited. Results on two-particle angular correlations over a broad range of pseudorapidity and azimuthal angle in pp collisions are presented. Underlying event activity are studied with different hard probes: tracks, trackjets, calorimeter clusters, or in Drell-Yan events.
