SUSY all hadronic stop search at 13TeV

A search for the direct production of supersymmetric scalar top-quark pairs, which decay directly to stable neutralinos and top-quarks which subsequently decay to an all-hadronic final state, is described. The results are based on 2.1fb-1 of 2015 13TeV run2 pp collision data. Sensitivity to the potential signal, over a range of scalar-top and neutralino masses, is obtained by explicitly identifying large missing momentum, MT2, bottom quark and the presence of all-hadronic topquark decays using a top-quark tagger.
