Abstract
We propose a new scheme for neutrino mass generation through a modification
of the standard Higgs mechanism implemented by introducing an unconventional
tiny vacuum breaking to the charged Higgs field. In this modified Higgs
mechanism, with identical particle spectrum as the standard electroweak model,
the lepton-Higgs Yukawa coupling Lagrangian would carry a modified lepton mass
matrix. Combining the latest data of particle experiments with this modified
lepton mass matrix enable us to locate the value of the parameter parametrizing
the extra perturbative Higgs vacuum breaking and produce masses for neutrinos
of three generations. We show that our results satisfy the constraints from
current physical experiments and cosmological observations. In the new Higgs
mechanism now we propose, the Higgs vacua are completely broken, such that, the
very minuteness of the extra Higgs vacuum breaking explains the origin of the
very minuteness of neutrino masses, while the relative greatness of the
standard Higgs vacuum breaking is recognized as the origin of the relative
greatness of charged lepton masses. This proposal can bring rich new physics to
Higgs-relevant problems in particle physics, besides injecting new inspiration
to the solution of massive neutrino problems.
