Cosmological constraints on the decay of heavy relics into neutrinos
Thomas Hambye, Marco Hufnagel, Matteo Lucca
A massive particle decaying into neutrinos in the early Universe is known to be less constrained than if it was decaying into other standard model particles. However, even if the d…
Dark matter electromagnetic dipoles: the WIMP expectation
Thomas Hambye, Xun-Jie Xu
We perform a systematic study of the electric and magnetic dipole moments of dark matter (DM) that are induced at the one-loop level when DM experiences four-fermion interactions w…
The domain of thermal dark matter candidates
Rupert Coy, Thomas Hambye, Michel H. G. Tytgat +1
We consider, in general terms, the possible parameter space of thermal dark matter candidates. We assume that the dark matter particle is fundamental and was in thermal equilibrium…
Seesaw determination of the dark matter relic density
Rupert Coy, Aritra Gupta, Thomas Hambye
In this article, we show that in the usual type-I seesaw framework, augmented solely by a neutrino portal interaction, the dark matter (DM) relic density can be created through fre…
