In this note, we advocate a new method for identifying gluino pair productionevents at the LHC. The method is motivated by and works for theories with heavysquarks and Wino-like LSPs (with nearly degenerate LSP and chargino). Suchtheories are well motivated and their gluinos typically have a O(50%) branchingratio to charged Winos. Observing the track of a long lived charged Winoproduced from gluino decay could give a clear identification of a gluino event.Charged Wino NLSPs produced in colliders can be long-lived enough to leave areconstructable high pT charged track before decaying into a soft pion (or asoft lepton) and the LSP, a signature with low SM background. By supplementingthe canonical gluino search strategy with a search for these stiff charginotracks, our results suggest it will be possible to find gluinos withsignificantly less luminosity. In addition, we describe a procedure forobtaining a kinematic measurement of the gluino mass using the three momenta ofthe reconstructed chargino tracks. With measurements of the gluino mass andcross section, it will be possible to determine the gluino spin, and confirmthat the excess events are indeed due to a spin 1/2 superpartner. It may alsobe possible to use these stiff Wino tracks to obtain an approximate measurementof the chargino mass, and therefore the LSP (dark matter) mass.
