MTGEN : Mass scale measurements in pair-production at colliders

Abstract

We introduce a new kinematic event variable MTGEN which can provide information relating to the mass scales of particles pair-produced at hadronic and leptonic colliders. The variable is of particular use in events with a large number of particles in the final state when some of those particles are massive and not detected, such as may arise in R-parity-conserving supersymmetry.

Also a little more info regarding MT2. v3 fixes one more typo. v4 included an Addendum highlighting a relevant result from a later paper (by other authors) which simplifies one of the key results of the paper]
