Flavor-specific scalar mediators
Brian Batell, Ayres Freitas, Ahmed Ismail +1
New singlet scalar bosons have broad phenomenological utility and feature prominently in many extensions of the Standard Model. Such scalars are often taken to have Higgs-like coup…
Thermal Dark Matter Through the Dirac Neutrino Portal
Brian Batell, Tao Han, David McKeen +1
We study a simple model of thermal dark matter annihilating to standard model neutrinos via the neutrino portal. A (pseudo-)Dirac sterile neutrino serves as a mediator between the…
Baryogenesis from Oscillations of Charmed or Beautiful Baryons
Kyle Aitken, David McKeen, Ann E. Nelson +1
We propose a model for CP violating oscillations of neutral, heavy-flavored baryons into antibaryons at rates which are within a few orders of magnitude of their lifetimes. The fla…
