Neutrino, Dark Matter and Higgs Portals for New Physics

Rahul Srivastava

Valencia, Spain

Neutrinos and dark matter both are of fundamental importance to the complete
understanding of our universe. Despite tremendous amount of theoretical as
well as experimental research over several decades, they are still poorly
understood.
The origin of neutrino mass and the nature and properties of dark matter
constitute a basic challenge in both astro and particle physics, whose
elucidation would bring a breakthrough in our understanding of nature. In this
talk I will discuss some of my recent work aimed at constructing, analyzing
and looking for experimental signatures of new physics models able to explain
neutrino properties while accounting for the cosmological dark matter. I will
also discuss some of my past and ongoing research aimed at exploiting the
synergy between the three main current experimental probes, namely, the
Higgs and collider physics, neutrino physics and dark matter to test and
constrain these scenarios with the ultimate aim of finding the elusive signatures of the new physics.
