Zusammenfassung: | We propose a predictive $Q_4$ flavored 2HDM model, where the scalar sector is
enlarged by the inclusion of several gauge singlet scalars and the fermion
sector by the inclusion of right handed Majorana neutrinos. In our model, the
$Q_4$ family symmetry is supplemented by several auxiliary cyclic symmetries,
whose spontaneous breaking produces the observed pattern of SM charged fermion
masses and quark mixing angles. The light active neutrino masses are generated
from an inverse seesaw mechanism at one loop level thanks to a remnant
preserved $Z_2$ symmetry. Our model succesfully reproduces the measured dark
matter relic abundance and is consistent with direct detection constraints for
masses of the DM candidate around $\sim$ 6.3 TeV. Furthermore, our model is
also consistent with the lepton and baryon asymmetries of the Universe as well
as with the muon anomalous magnetic moment |
