Multi-component dark matter from a hidden gauged SU(3)
Stephen Godfrey, Alexandre Poulin
We studied Dark Matter (DM) phenomenology with multiple DM species consisting of both scalar and vector DM particles in the Hidden Gauged SU(3) model of Arcadi et al. Because of th…
Dark Matter freezeout in modified cosmological scenarios
Alexandre Poulin
We study the effects of modifying the expansions history of the Universe on Dark Matter freezeout. We derived a modified Boltzmann equation for freeze-out for an arbitrary energy d…
Multi-component dark matter from a hidden gauged SU(3)
Alexandre Poulin, Stephen Godfrey
We study Dark Matter (DM) phenomenology with multiple DM species consisting of both scalar and vector DM particles. More specifically, we study the Hidden Gauged SU(3) model of Arc…
Real singlet scalar dark matter extension of the Georgi-Machacek model
Robyn Campbell, Stephen Godfrey, Heather E. Logan +1
The Georgi-Machacek model extends the Standard Model Higgs sector with the addition of isospin-triplet scalar fields in such a way as to preserve the custodial symmetry. The presen…
Implications of the observation of dark matter self-interactions for singlet scalar dark matter
Robyn Campbell, Stephen Godfrey, Heather E. Logan +2
Evidence for dark matter self-interactions has recently been reported based on the observation of a spatial offset between the dark matter halo and the stars in a galaxy in the clu…
