Proposing a new LHC search for light compressed stop squarks
Paper i proceeding, 2015

The LHC searches for light compressed stop squarks have resulted in considerable bounds in the case where the stop decays to a neutralino and a charm quark. However, in the case where the stop decays to a neutralino, a bottom quark and two fermions via an off-shell W-boson, there is currently an unconstrained region in the stop-neutralino mass plane, still allowing for stop masses around 100 GeV. In this note we will propose a new monojet-like search for light stops, optimized for the four-body decay mode, in which at least one b-tagged jet is required. We show that, already by using the existing 8 TeV LHC data set, such a search would cover the entire unconstrained region. This note is based on ref.
