Description
The stransverse mass variable MT2 was originally proposed for the study of SUSY-like events at hadron colliders in which N=2 parent particles are produced and then decay semi-invisibly. Here we consider the generalization to the case of N≥3 semi-invisibly decaying parent particles. We introduce the corresponding class of kinematic variables MTN and illustrate their mathematical properties. Many of the celebrated features of the MT2 kinematic endpoint are retained in this more general case, including the ability to measure the mass of the invisible daughter particle from the stransverse mass kink.
