Descrição: We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known results for the phase diagram of the effective theory. We find regions of the parameter space where the theory exhibits a first-order phase transition. In particular, our findings are consistent with previous perturbativeresults suggesting that the primary signature of a first-order EWPTin the 2HDM is mA0 >m H0 þmZ. SCOAP3. publishedVersion
