Color Breaking Baryogenesis
Michael J. Ramsey-Musolf, Peter Winslow, Graham White
We propose a scenario that generates the observed baryon asymmetry of the Universe through a multi--step phase transition in which SU(3) color symmetry is first broken and then res…

Singlet-Catalyzed Electroweak Phase Transitions in the 100 TeV Frontier
Ashutosh V. Kotwal, Michael J. Ramsey-Musolf, Jose Miguel No +1
We study the prospects for probing a gauge singlet scalar-driven strong first order electroweak phase transition with a future proton-proton collider in the 100 TeV range. Singlet-…

The Higgs Portal and Cosmology
Ketevi Assamagan, Chien-Yi Chen, John Paul Chou +19
Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal inter…
