寻找{ \surd }s = 7 TeV强末态的新物理

Search for New Physics at {\surd}s = 7 TeV in Hadronic Final States with Missing Transverse Energy and Heavy Flavor

Bart Butler

摘要:

在{ \surd }s = 7 TeV质子-质子碰撞中,寻找了具有大的横动量缺失、重味喷注候选者和无轻子(e,μ)的事件中的超对称粒子.在大型强子对撞机上的ATLAS实验记录的对应于积分亮度为0.83 fb^-1的数据样本中,没有观察到相对于标准模型过程的预测有明显的过量。与模型无关的生产截面上限在简化模型和常规极限的情况下提供。

英文摘要:

A search for supersymmetric particles in events with large missing transverse momentum, heavy flavor jet candidates and no leptons (e,μ) in {\surd}s = 7 TeV proton-proton collisions is presented. In a data sample corresponding to an integrated luminosity of 0.83 fb^-1 recorded by the ATLAS experiment at the Large Hadron Collider, no significant excess is observed with respect to the prediction for Standard Model processes. Model-independent production cross section upper limits are provided in the context of simplified models as well as conventional limits.
