Abstract

We introduce a new observable, 'gluino stransverse mass', which is an application of the Cambridge mT2m_{T2} variable to the process where gluinos are pair produced in proton-proton collision and each gluino subsequently decays into two quarks and one LSP, i.e.g~g~qqχ~10 qqχ~10i.e. \tilde{g}\tilde{g} \to qq\tilde\chi_1^0\ qq\tilde\chi_1^0. We show that the gluino stransverse mass can be utilized to measure the gluino and the lightest neutralino masses separately, and also the (1st and 2nd generation) squark masses if lighter than the gluino mass, thereby providing a good first look at the pattern of sparticle masses experimentally.
