Abstract
We present a TeV scale seesaw mechanism for exploring the dark matter and neutrino phenomenology in the light of recent neutrino and cosmology data. A different realization of the Inverse seesaw (ISS) mechanism with A4 flavor symmetry is being implemented as a leading contribution to the light neutrino mass matrix which usually gives rise to vanishing reactor mixing angle θ13. Using a non-diagonal form of Dirac neutrino mass matrix and 3σ values of mass square differences we parameterize the neutrino mass matrix in terms of Dirac Yukawa coupling “y”. We then use type II seesaw as a perturbation which turns out to be active to have a non-vanishing reactor mixing angle without much disturbing the other neutrino oscillation parameters. Then we constrain a common parameter space satisfying the non-zero θ13, Yukawa coupling and the relic abundance of dark matter. Contributions of neutrinoless double beta decay are also included for standard as well as non-standard interaction. This study may have relevance in future neutrino and Dark Matter experiments.
Highlights
The link between neutrino oscillation and modern cosmology needs an elucidation since both of them infer physics beyond Standard Model (BSM)
It will be more fascinating if the discovery of neutrino oscillation and the existence of dark matter (DM) can be framed within the same particle physics model
Is an attempt to search for a theory which is responsible for explaining neutrino phenomenology and Dark Matter (DM) stability as well
Summary
The link between neutrino oscillation and modern cosmology needs an elucidation since both of them infer physics beyond Standard Model (BSM). The most successful Standard Model (SM) of particle physics too has not been able to furnish any signature of DM candidates and their properties This is one of the pressing problems in both high energy physics and cosmology. Searching for a concrete realization to provide a hint towards physics BSM will be of utmost interest It will be more fascinating if the discovery of neutrino oscillation and the existence of DM can be framed within the same particle physics model. In addition to the ISS we are working with the Type II seesaw mechanism which turns out to be instrumental to have the non-vanishing reactor mixing angle Both the inverse and type II seesaw are realized adopting the A4 flavor symmetry.
