Electroweak phase transition in two Higgs doublet models
Electroweak phase transition in two Higgs doublet models
We reexamine the strength of the first-order phase transition in the electroweak theory supplemented by an extra Higgs doublet. The finite-temperature effective potential ${V}_{\mathrm{eff}}$ is computed to one-loop order, including the summation of ring diagrams, to study the ratio ${\ensuremath{\varphi}}_{c}{/T}_{c}$ of the Higgs field VEV to the critical temperature. We …
