LHC上SUSY粒子的简单质量重建技术

A Simple Mass Reconstruction Technique for SUSY particles at the LHC

N. Kersting

摘要:

通常情况下,由重粒子的可见衰变产物构造的不变质量可能仅在某个运动学配置中达到最大值(或最小值)-这一事实可以用于从观测到的衰变产物动量重建相关的粒子质量。举例说明了在大型强子对撞机上由多轻子终态进行的MSSM中性伴子和电荷伴子质量重建。

英文摘要:

It is often true that an invariant mass constructed from visible decay products of a heavy particle may attain a maximum(or minimum) for a certain kinematic configuration only -- this fact can be used to reconstruct relevant particle masses from observed decay product momenta of events near the invariant mass endpoint. MSSM neutralino and chargino mass reconstruction at the LHC from multi-lepton endstates is illustrated by way of example.
