Abstract: (arXiv)
We present a general solution to the long standing problem of determining the masses of pair-produced, semi-invisibly decaying particles at hadron colliders. We define two new transverse kinematic variables, and , which are suitable one-dimensional projections of the contransverse mass . We derive analytical formulas for the boundaries of the kinematically allowed regions in the and parameter planes, and introduce suitable variables and to measure the distance to those boundaries on an event per event basis. We show that the masses can be reliably extracted from the endpoint measurements of and (or ). We illustrate our method with dilepton events at the LHC.- 13.85.Ni
