Singlet-doublet dark matter beyond freeze-out
Prudhvi N. Bhattiprolu, Aaron Pierce, Alexander Takla
The Singlet-Doublet fermion model of dark matter is an economical weak-scale dark matter model that realizes the dark matter abundance through interactions with the electroweak bos…
Chasing higgsino dark matter at colliders in the neutrino fog era
Prudhvi N. Bhattiprolu, Stephen P. Martin, James D. Wells
Higgsinos can be the lightest supersymmetric particles, allowing for either a full or partial dark matter interpretation, with the correct thermal freeze-out abundance obtained for…
Singlet-doublet dark matter revisited
Prudhvi N. Bhattiprolu, Evan Petrosky, Aaron Pierce
The singlet-doublet model is an economical model of weakly interacting dark matter. We revisit it in light of improved dark matter direct detection limits. We characterize the now…
Sub-MeV Dark Sink Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Evan Petrosky +1
A Dark Sink uses dark-sector interactions to siphon energy from dark matter to lighter dark degrees of freedom, i.e. dark radiation. Here, we extend dark matter models containing a…
A sensitivity target for an impactful Higgs boson self coupling measurement
Prudhvi N. Bhattiprolu, James D. Wells
We argue that a measurement of the Higgs boson self-coupling becomes particularly meaningful in a large and important class of theories when its sensitivity is within 40\% of its S…
A Dark Sink Enhances the Direct Detection of Freeze-in Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Aaron Pierce
We describe a simple dark sector structure which, if present, has implications for the direct detection of dark matter (DM): the Dark Sink. A Dark Sink transports energy density fr…
