Constraints on new physics from baryogenesis and Large Hadron Collider data

We demonstrate the power of constraining theories of new physics by insisting that they lead to electroweak baryogenesis, while agreeing with current data from the Large Hadron Collider. The general approach is illustrated with a singlet scalar extension of the standard model. Stringent bounds can a...

Description
Summary:We demonstrate the power of constraining theories of new physics by insisting that they lead to electroweak baryogenesis, while agreeing with current data from the Large Hadron Collider. The general approach is illustrated with a singlet scalar extension of the standard model. Stringent bounds can already be obtained, which reduce the viable parameter space to a small island.
