本文研究了质子-质子碰撞中类号双μ子末态的微观黑洞。这些数据是2012年在大型强子对撞机上用ATLAS探测器收集的,对应的积分光度为。使用高轨道多重性要求,预测来自标准模型过程的背景事件,并且没有观察到。这一结果是在低尺度重力模型和95% C.L.微观黑洞质量的下限是针对不同的模型假设设定的。
A search is presented for microscopic black holes in a like-sign dimuon final state in proton–proton collisions at. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated luminosity of. Using a high track multiplicity requirement,background events from Standard Model processes are predicted and none observed. This result is interpreted in the context of low-scale gravity models and 95% C.L. lower limits on microscopic black hole masses are set for different model assumptions.
