Abstract

We propose an inclusive analysis of a stransverse mass (m T2) using a hemisphere method. The hemisphere method is an algorithm to group collinear and high p T particles and jets, assuming that there are two of such groups in a event. An inclusive m T2 is defined as a function of an unknown LSP mass, two hemisphere momenta, and missing transverse momentum. Kinematical end points of m T2 distributions provide information on sparticle masses. We perform a Monte Carlo simulation to study the inclusive m T2 distribution at the LHC. We show that the end point of the inclusive m T2 distribution as a function of a test LSP mass has a kink-like structure around the true LSP mass. We find that the inclusive analysis is useful for obtaining information on the heaviest of squark/gluino.
