Lepton universality violation in the minimal flipped 331 model

We perform a detailed study of the b -> c tau nu and b -> sl+l- processes in a minimal flipped 331 model based on the SU(3)C x SU(3)L x U(1)X gauge symmetry. The non-universal SU(3)L x U(1)X symmetry in the lepton sector gives rise to non-universal neutra
