Forbidden Dark Matter Annihilations into Standard Model Particles
Raffaele Tito D'Agnolo, Di Liu, Joshua T. Ruderman +1
We present kinematically forbidden dark matter annihilations into Standard Model leptons. This mechanism precisely selects the dark matter mass that gives the observed relic abunda…

Thermal Relic Targets with Exponentially Small Couplings
Raffaele Tito D'Agnolo, Duccio Pappadopulo, Joshua T. Ruderman +1
If dark matter was produced in the early Universe by the decoupling of its annihilations into known particles, there is a sharp experimental target for the size of its coupling. We…

Exponentially Light Dark Matter from Coannihilation
Raffaele Tito D'Agnolo, Cristina Mondino, Joshua T. Ruderman +1
Dark matter may be a thermal relic whose abundance is set by mutual annihilations among multiple species. Traditionally, this coannihilation scenario has been applied to weak scale…
