Gauged Flavour Symmetry in Pati-Salam — •Florian Hartmann, Thorsten Feldmann, Wolfgang Kilian, and Christoph Luhn — Universität Siegen, Germany

We consider a grand unified theory based on the left-right symmetric Pati-Salam group. The maximal flavour symmetry of the gauge-kinetic terms, SU(3)× SU(3), is broken spontaneously by vacuum expectation values. The model contains additional fermionic quark (and lepton) partners, which introduce new sources of flavour violation in both, left- and right-handed quark transitions. These additional fermions cancel the flavour gauge anomalies and allow us to consider only renormalizable operators. The top and bottom partner can have a mass in the TeV range.
