Algebraic Singularity Method for Mass Measurements with Missing Energy

Abstract

We propose a novel generalized method for mass measurements based on phase space singularity structures that can be applied to any event topology with missing energy. Our method subsumes the well-known end-point and transverse mass methods and yields new techniques for studying "missing particle" events, such as the double chain production of stable neutral particles at the LHC.
