Abstract
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 interactions may contain the ingredients for a strong first order electroweak phase transition as well as new CP-violating interactions as needed for electroweak baryogenesis. These interactions may also allow for a viable dark matter candidate. We survey the opportunities for probing the Higgs portal as it relates to these questions in cosmology at the LHC and possible future colliders.
Comment: 33 pages, 7 figures. Summarization of the landscape of possibilities surveyed at the "Unlocking the Higgs Portal" Workshop held at the Amherst Center for Fundamental Interactions (ACFI) in May 2014
