Accidentally Stable Dark Matter in a Parity Solution to the Strong CP Problem
Matthew J. Baldwin, Keisuke Harigaya, Isaac R. Wang
Parity symmetry, with an extended gauge group , can solve the strong CP problem. In particular, the model where $SU(2)_R\times…

Probing the Cosmic Axion Background via Axion-Photon Conversion in Filaments
Duncan Rocha, Gordan Krnjaic, Matthew J. Baldwin
The cosmic axion background (CaB) is a hypothetical population of relativistic axions produced in the early universe. If the CaB is produced from dark matter decays, the axions in…

Upper Bound on Parity Breaking Scale for Doublet WIMP Dark Matter
Matthew J. Baldwin, Keisuke Harigaya, Isaac R. Wang
We consider weakly interacting massive particle (WIMP) dark matter in a Parity solution to the strong CP problem. The WIMP phenomenology can be drastically affected by the presence…
