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…
Dark Matter Catalyzed Baryon Destruction
Yohei Ema, Robert McGehee, Maxim Pospelov +1
WIMP-type dark matter may have additional interactions that break baryon number, leading to induced nucleon decays which are subject to direct experimental constraints from proton…
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…
Finite Bubble Statistics Constrain Late Cosmological Phase Transitions
Gilly Elor, Ryusuke Jinno, Soubhik Kumar +2
We consider first order cosmological phase transitions (PT) happening at late times, below Standard Model (SM) temperatures GeV. The inherently stochastic nat…
Freezing-in hadrophilic dark matter at low reheating temperatures
Prudhvi N. Bhattiprolu, Gilly Elor, Robert McGehee +1
If the reheating temperature at the end of inflation is low, of order 10 MeV, then dark matter produced through ultraviolet freeze-in has a large direct detection cross section. We…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
