Predictive Signatures Of Supersymmetry: Measuring The Dark Matter Mass And Gluino Mass With Early Lhc Data, Daniel Feldman, Katherine Freese, Pran Nath, Brent D. Nelson, Gregory Peim

Brent Nelson

We present a focused study of a predictive unified model whose measurable consequences are immediately relevant to early discovery prospects of supersymmetry at the LHC. ATLAS and CMS have released their analysis with 35  pb-1 of data and the model class we discuss is consistent with this data. It is shown that with an increase in luminosity, the LSP dark matter mass and the gluino mass can be inferred from simple observables such as kinematic edges in leptonic channels and peak values in effective mass distributions. Specifically, we consider cases in which the neutralino is of low mass and where …
