LHC-Phenomenology of Leptoquarks in a SUSY GUT — •Daniel Wiesler and Jürgen Reuter — Hermann-Herder-Str. 3, Physikalisches Institut, Albert-Ludwigs-Universität Freiburg

We present the LHC-phenomenology of exotic scalar leptoquarks and fermionic leptoquarkinos in context of an E6 SUSY GUT. Feynman rules for the interaction of these exotics were derived and implemented into the Monte-Carlo event generator WHIZARD. The Production mechanisms are investigated and the corresponding cross-sections are calculated using WHIZARD and cross-checked with earlier studies. Exclusive final states for LHC searches for scalar leptoquarks are classified and cuts are developed with respect to the optimization of signal- to-background ratios. In the fermionic leptoquarkino sector we introduce a method to measure mass differences for sparticles and apply it to our specific scenario. The resulting mass edges substantially differ from the usual SUSY ones in the literature and can provide an insight into the underyling (SUSY-) GUT. Assuming an additional flavour symmetry, striking OSDF lepton contributions from scalar leptoquarks allow for spectacular signatures at the LHC and can serve as remnants of high-scale flavour physics.
