Charged right-handed currents in the leptoquark-bilepton flavordynamics   chiral models
  Flavordynamics chiral models of leptoquark fermions and bilepton gauge bosons with masses up to about 1 TeV, although coincident at low energy with the standard model, address the question of fermion mass hyerarchy and explain the flavor question. The presence of charged right-handed weak currents coupled to bileptons, which we point out herein, is another remarkable feature of these chiral theories.
