Abstract Electroweak and horizontal interactions are unified with the groupSU(6) L ⊗U(1) Y for three generations. The horizontal gauge group suggested from low energy phenomenology isSU(2) H . This model does not contain exotic quarks, but exotic leptons are needed in order to make it anomaly-free. The breaking of the symmetry gives, in a natural way, heavy masses for exotic leptons and a BCS mass matrix for the up quarks, which implies that at tree level only the top quark gets a mass of orderM W . The see-saw mechanism generates tiny masses for the three known neutrinos. The remaining of the known fermion masses are light, because they can be generated only as radiative corrections.
