The Pati-Salam Supersymmetric SM (PSSSM)

Abstract

Grand Unified Theories based on an E6 gauge group embed all Higgs- and matter fields within one 27 dimensional fundamental representation. In addition each 27 contains a right handed neutrino, an NMSSM-like standard model singlet and a pair of exotic particles, that couple quarks to leptons. The extended particle content spoils simple gauge unification as in the MSSM. By embedding the SM into a Pati-Salam gauge group above 10^16 GeV, one obtains a unification below the Planck-scale. We present a Markov chain Monte-Carlo algorithm to systematically scan the high dimensional parameter space and calculate low-energy spectra, as well as first results of our studies of the LHC phenomenology of leptoquarks and leptoquarkinos with the event generator WHIZARD.
