钨酸铅晶体阵列的能量重建及π~0/γ分辨
Energy reconstruction and π~0/γ identification in PWO crystals
【摘要】 通过模拟CMS电磁量能器中钨酸铅晶体阵列的物理响应,全面分析了其性能。对各种可能的能量重建方法及其相应的能量分辨本领进行了仔细的研究和探讨。并通过神经元网络方法研究了在高动量情况下对g事例中p0本底的排除本领。
【Abstract】 General properties for PWO crystals in the electromagnetic calorimeter of CMS were studied with detailed simulation. Various energy reconstruction methods and related energy resolution were compared. The capability of identifying neutral pion and gamma at high momentum was also studied and discussed by using Neural Networks.
