Abstract

摘要

A beyond the Standard Model neutrino sector can give arise to both
Dark Matter candidates and mechanisms that explains the origin of
the finite neutrino masses. When the dark matter hails from the
neutrino sector, its annihilation and decay can be differentiated
from those of typical weakly interacting candidate, giving unique
signals in high energy cosmic ray observations, like Fermi-LAT and
IceCube. In this talk I will discuss two topics: (1) how the
combination of direct and indirect search results can differentiate
a neutrino-originated dark matter from a `conventional' WIMP dark
matter in the content of a popular supersymmetric U(1)' model;
(2) in light of light right-handed neutrino(s), the constraint on
the associated dark matter's scattering cross-section from Solar
gamma ray and neutrino measurements, which can be very competitive
to direct detection results over a significant range of dark matter
mass. I will also comment on the current collider bounds on the
right-handed neutrino properties.
