用ATLAS探测器测量非弹性p-p事例的性质

Measurement of the properties of inelastic p-p events with the ATLAS detector

Maaike Limper

摘要:

新的测量提出了从质子-质子碰撞在sqrt(s)= 7 TeV记录与ATLAS探测器在LHC。最小偏差分布测量在不同的相空间区域,并与蒙特卡罗模型预测。基本事件中的活动是相对于事件中具有最高横向动量的轨道来测量的。研究带电粒子之间的角度相关性以提供模型敏感的测量。

英文摘要:

New measurements are presented from proton-proton collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC. Minimum bias distributions are measured in distinct phase-space regions and compared with Monte Carlo model predictions. Activity in the underlying event is measured with respect to the track with the highest tranverse momentum in the event. Angular correlations between charged particles are studied to provide model-sensitive measurements.
