abstract
Models based on the extended $SU(3)_{C}\times SU(3)_{L}\times U(1)_{X}$ (331) gauge group usually follow a common pattern: two families of left-handed quarks are placed in anti-triplet representations of the $SU(3)_{L}$ group; the remaining quark family, as well as the left-handed leptons, are assigned to triplets (or vice-versa). In this work we present a flipped 331 model where this scheme is reversed: all three quarks families are in the same representation and it is the lepton families which are discriminated by the gauge symmetry. We discuss fermion masses and mixing, as well as $Z'$ interactions, in a minimal model implementing this idea.

Natural neutrino sector in a 331-model with Froggatt-Nielsen mechanism
Adding right-handed neutrinos to the Froggatt-Nielsen 331 model realizes a double seesaw with sub-eV active neutrinos, keV sterile neutrinos, and TeV-scale heavy neutrinos that fits oscillation data in three benchmark points.

Radiative corrections to the $\rm S, T, U$ parameters and their impact on the $W$ boson mass in the 331 model
For the beta=-sqrt(3) 331 model, electroweak precision data allow v3 between roughly 1.5 and 2.3 TeV and can reproduce the CDF W mass shift for v3 in 1.8-2.3 TeV, provided collider bounds on new gauge bosons are model...
