A Simple Mass Reconstruction Technique for SUSY particles at the LHC

Understand

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.
