Walter Hopkins – Using Direct Stop Searches at ATLAS to Constrain the Parameter Space of Supersymmetric Models
September 1, 2015 @ 4:00 pm - 5:00 pm
Abstract:
A summary of the search for direct stop production in the 0-lepton channel is presented using 20 
TeV data collected with the ATLAS experiment at the LHC. One of the stop decay modes considered is a stop decay to a top and a neutral lightest supersymmetric particle (LSP) resulting in signature with four or more jets and large missing energy. No excess is observed above the background expectation and limits are set on the stop and LSP masses and are presented as a function of stop decay branching fraction, combining the results from the 0 and 1-lepton channels. Additionally, the results are interpreted to confine the much larger parameters space of a more general supersymmetric model. Finally, outlook for stop searches for the LHC Run 2 will also be discussed.
