Precision determination of invisible-particle masses at the CERN LHC

Abstract:

We develop techniques to determine the mass scale of invisible particles pair-produced at hadron colliders. We employ the constrained mass variable m2C, which provides an event-by-event lower bound to the mass scale given a mass difference. We complement this variable with a new variable m2C,UB which provides an additional upper bound to the mass scale and demonstrate its utility with a realistic case study of a supersymmetry model. These variables together effectively quantify the "kink" in ...
