利用8 TeV pp碰撞末态两个同号孤立轻子事件寻找新物理

Search for new physics using events with two same-sign isolated leptons in the final state in pp collisions at 8 TeV

Santiago Folgueras

摘要:

基于喷流和一对孤立的同号轻子的事件,进行了对新物理的探索。使用CMS实验收集的质子-质子碰撞数据样本获得的结果在LHC的质心能量为8 TeV,对应于积分亮度为19.5毫微微电子能垒。为了对标准模型之外的各种可能的信号敏感,多个搜索区域由缺失的横向能量、强子能量、喷注和b夸克喷注的数量定义。没有超过标准模型的背景预期被观察到,并限制了新物理学的一些模型。

英文摘要:

A search for new physics is performed based on events with jets and a pair of isolated, same-sign leptons. The results are obtained using a sample of proton-proton collision data collected by the CMS experiment at a centre-of-mass energy of 8 TeV at the LHC, corresponding to an integrated luminosity of 19.5 inverse femtobarns. In order to be sensitive to a wide variety of possible signals beyond the standard model, multiple search regions defined by the missing transverse energy, the hadronic energy, the number of jets and b-quark jets. No excess above the standard model background expectation is observed and constraints are set on a number of models for new physics.
