Query: Realistic $\mathrm{SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$ model with a
  type II Dirac neutrino seesaw mechanism   Here we propose a realistic $\mathrm{SU(3)_c \otimes SU(3)_L \otimes U(1)_X}$
electroweak gauge model with enlarged Higgs sector. The scheme allows for the
natural implementation of a type II seesaw mechanism for Dirac neutrinos, while
charged lepton and quark masses are reproduced in a natural way thanks to the
presence of new scalars. The new $\mathrm{SU(3)_c \otimes SU(3)_L \otimes
U(1)_X}$ energy scale characterizing neutrino mass generation could be
accessible to the current LHC experiments.
