Abstract

The first run of the LHC has been tremendously successful, having discovered the Higgs boson as well as having set stringent limits on superpartner masses. This has severely constrained supersymmetric models. A consistent scenario based on LHC data suggests that the third generation sfermions, Higgsinos and the gluino must be light while the first two generation sfermions are heavy. Furthermore, an extra contribution to the Higgs quartic coupling is needed to explain the 126 GeV Higgs mass. Interestingly this spectrum can naturally arise from supersymmetry breaking in a warped geometry where the sfermion spectrum is related to the fermion mass hierarchy. Various possible scenarios are reviewed and compared with the data from the first run at the LHC.
