Query: Strong Electroweak Phase Transitions in the Standard Model with a
  Singlet   It is well known that the electroweak phase transition (EWPhT) in extensions
of the Standard Model with one real scalar singlet can be first-order for
realistic values of the Higgs mass. We revisit this scenario with the most
general renormalizable scalar potential systematically identifying all regions
in parameter space that develop, due to tree-level dynamics, a potential
barrier at the critical temperature that is strong enough to avoid sphaleron
wash-out of the baryon asymmetry. Such strong EWPhTs allow for a simple
mean-field approximation and an analytic treatment of the free-energy that
leads to very good theoretical control and understanding of the different
mechanisms that can make the transition strong. We identify a new realization
of such mechanism, based on a flat direction developing at the critical
temperature, which could operate in other models. Finally, we discuss in detail
some special cases of the model performing a numerical calculation of the
one-loop free-energy that improves over the mean-field approximation and
confirms the analytical expectations.
