Triple seesaw mechanism
On fitting the type II seesaw mechanism into the type I seesaw mechanism, we
obtain a formula to the neutrino masses which get suppressed by high-scale
in its denominator. As a result, light neutrinos are naturally obtained
with new physics at TeV scale. As interesting consequence, the mechanism may be
directly probed at the LHC by directly producing the TeV states intrinsic of
the mechanism. We show that the 3-3-1 model with right-handed neutrinos
realizes naturally such seesaw mechanism.Comment: About 13 pages, no figure
Neutrino Masses and Absence of Flavor Changing Interactions in the 2HDM from Gauge Principles
We propose several Two Higgs Doublet Models with the addition of an Abelian
gauge group which free the usual framework from flavor changing neutral
interactions and explain neutrino masses through the seesaw mechanism. We
discuss the kinetic and mass-mixing gripping phenomenology which encompass
several constraints coming from atomic parity violation, the muon anomalous
magnetic moment, rare meson decays, Higgs physics, LEP precision data,
neutrino-electron scattering, low energy accelerators and LHC probes.Comment: 54 pages, 10 figure
