Search for a supersymmetric partner to the top quark in final states with jets and missing transverse momentum at √s=7TeV with the ATLAS detector
A search for direct pair production of supersymmetric top squarks (t 1 ) is presented, assuming the t 1 decays into a top quark and the lightest supersymmetric particle, χ10, and that both top quarks decay to purely hadronic final states. A total of 16 (4) events are observed compared to a predicted...
