Probing the Phenomenology of Dark Matter from Decoupled Freeze-Out
Geneviève Bélanger, Aoife Bharucha, Sreemanti Chakraborti +2
We consider a model of dark matter where the mediator corresponds to a superposition of a scalar and pseudoscalar, and the scenario where, after reheating, the number densities of…

Rekindling s-Wave Dark Matter Annihilation Below 10GeV with Breit-Wigner Effects
Geneviève Bélanger, Sreemanti Chakraborti, Cédric Delaunay +1
Velocity-independent (s-wave) annihilation of thermal Dark Matter is ruled out by CMB data for masses below 10GeV, effectively ruling out the possibility of indirectly detecting it…
