在sqrt(s)= 8 TeV质子-质子碰撞中寻找多喷流和丢失横动量末态的新物理

Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at sqrt(s) = 8 TeV

CMS Collaboration

摘要:

利用LHC CMS探测器收集的积分亮度为19.5个反飞秒的数据样本,在sqrt(s)= 8 TeV的质子-质子碰撞中产生的具有大的缺失横向动量的多喷流事件中进行新物理的搜索.数据样本被分为三个喷流多重性类别(3-5,6-7,和8个或更多的射流),并进一步研究了两个变量的箱:射流横向动量和失踪的横向动量的标量和。观察到的各种类别的事件数量与标准模型过程预期的背景一致。给出了夸克和胶子对产生的几种简化超对称模型的排斥极限。

英文摘要:

A search for new physics is performed in multijet events with large missing transverse momentum produced in proton-proton collisions at sqrt(s) = 8 TeV using a data sample corresponding to an integrated luminosity of 19.5 inverse femtobarns collected with the CMS detector at the LHC. The data sample is divided into three jet multiplicity categories (3-5, 6-7, and 8 or more jets), and studied further in bins of two variables: the scalar sum of jet transverse momenta and the missing transverse momentum. The observed numbers of events in various categories are consistent with backgrounds expected from standard model processes. Exclusion limits are presented for several simplified supersymmetric models of squark or gluino pair production.
