用ATLAS探测器寻找长寿命粒子

Search for long-lived particles with the ATLAS detector

Shimpei Yamamoto

摘要:

在标准模型之外的几种情况下,由于运动学约束、守恒量子数或弱耦合,预测了重的长寿命粒子。这些粒子可能通过异常的能量损失、出现或消失的轨道、位移的顶点、轻子喷流特征、长飞行时间或晚期量热能量沉积来识别。这篇文章总结了最近的结果搜索重长寿命粒子的ATLAS探测器使用PP碰撞数据在一个质心能量为8 TeV。

英文摘要:

Several scenarios beyond the Standard Model predict heavy long-lived particles as a result of a kinematic constraint, a conserved quantum number or a weak coupling. Such particles are possibly identified based on the detection through abnormal energy losses, appearing or disappearing tracks, displaced vertices, lepton-jet signatures, long time-of-flight or late calorimetric energy deposits. This contribution summarizes recent results of searches for heavy long-lived particles with the ATLAS detector using pp collision data at a center of mass energy of 8 TeV.
