Dark Photons from Perturbative Decay of a Misaligned Higgs Field
James M. Cline, Gonzalo Herrera, Jean-Samuel Roux
We reconsider the production of dark photons as dark matter, from the perturbative decay of a dark Higgs field , that is stochastically misaligned from the minimum of its p…

Neutrinos as Dark Matter

Active neutrinos in standard cosmology were ruled out as a dark matter candidate in the 1980's. The reason is twofold: they are too light to account for the observed energy density…

Dark Sector Electroweak Baryogenesis In Light Of The Galactic Center Excess
Jean-Samuel Roux, James M. Cline
We revisit a model of electroweak baryogenesis that includes a dark matter candidate, and sequesters the new CP violation required to produce the baryon asymmetry in a dark sector.…
