String completion of an SU(3)c⊗SU(3)L⊗U(1)X electroweak model
The extended electroweak SU(3)c⊗SU(3)L⊗U(1)X symmetry framework “explaining” the number of fermion families is revisited. While 331-based schemes can not easily be unified within the conventional field theory sense, we show how to do it within an approach based on D-branes and (un)oriented open stri...
