First-Order Electroweak Phase Transition and Baryogenesis from a Naturally Light Singlet Scalar
We investigate a minimal singlet-scalar extension to the Standard Model that achieves a strong first-order electroweak phase transition. The singlet can be naturally light because of an approximate shift symmetry and no extra hierarchy problem beyond that of the Standard Model Higgs is introduced. W...
