用ATLAS探测器在sqrt(s)= 8 TeV的14.3 fb^-1 pp碰撞中寻找同号双轻子和b喷注事件的异常产生

Search for anomalous production of events with same-sign dileptons and b jets in 14.3 fb^-1 of pp collisions at sqrt(s) = 8 TeV with the ATLAS detector

摘要:

搜索奇异的过程,最终状态包含至少一个b喷流,相当大的失踪横向动量,和一对轻子具有相同的电荷。利用大型强子对撞机上ATLAS探测器记录的sqrt(s)=8 TeV的pp碰撞的14.3 fb^-1样本,没有观察到明显超出背景预期的事件。该观察结果被解释为限制了标准模型之外的几个信号假设,并且将信号假设相关参数的限值设定为95%置信水平。

英文摘要:

A search is presented for exotic processes that result in final states containing jets including at least one b jet, sizable missing transverse momentum, and a pair of leptons with the same electric charge. Using a sample of 14.3 fb^-1 of pp collisions at sqrt(s) =8 TeV recorded by the ATLAS detector at the Large Hadron Collider, no significant excess of events over the background expectation is observed. This observation is interpreted as constraining several signal hypotheses beyond the Standard Model and limits are set at 95% confidence level on relevant parameters of the signal hypotheses.
