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.
