CMS的正向物理学

Forward Physics at CMS

Benoit Roland

摘要:

对正演过程的研究是对标准模型的重要检验,也是蒙特卡罗整定的重要输入。本文给出了三种质心能值($\sqrt{s}$ = 0.9 TeV、2.36 TeV和7 TeV)下CMS正向赝快度区的能流测量结果,即$3.15 < \vert η\vert < 4.9$.正向能量流的测量最小偏差事件和事件与中央dijet系统的横向能量提供了一个硬标度。的能量流进行了比较,不同的Monte Carlo模型与不同的多部分子相互作用计划。本文研究了$\sqrt{s}$ = 7 TeV时在赝快度范围$3.2 < \vert η\vert < 4.7$内的前向喷流。

英文摘要:

Studies of forward processes are important tests of the standard model and inputs for Monte Carlo tuning. A measurement of the energy flow in the forward pseudorapidity region of CMS, $3.15 < \vert η\vert < 4.9$, is presented for 3 values of the centre-of-mass energy $\sqrt{s}$ = 0.9 TeV, 2.36 TeV and 7 TeV. The forward energy flow is measured for minimum bias events and for events with a central dijet system the transverse energy of which provides a hard scale. The energy flow is compared to various Monte Carlo models with different multiparton interaction schemes. A study of forward jets in the pseudorapidity range $3.2 < \vert η\vert < 4.7$ is presented for $\sqrt{s}$ = 7 TeV.
