A new anomaly-free flipped 341 model

Abstract

A new flipped [Formula: see text] model without exotic electric charges is proposed. All the quark families are arranged in the same representation while lepton generations are in different representations leading to a tree level FCNC. Moreover, it is shown that the cancellation of the triangle gauge anomalies requires new additional leptons a 10-plet and a quadruplet. All fermion masses have been also discussed. Furthermore, using the most recent experimental data of the branching ratios of [Formula: see text] and [Formula: see text] rare decay modes, stringent bounds on the heavy neutral bosons masses and the muon-electron mixing matrix element are obtained.
