Query: First Order Phase Transition in a Two Higgs-doublet Model with
  $M_{h}>M_{W}$   We study the 3d effective field theory of a weakly coupled two Higgs-doublet
scalar model at high temperature. Our model has three scalar quartic couplings
and an $O(4)$ symmetry which is spontaneously broken by a nonzero scalar field
$vev$ at zero temperature. Using high temperature perturbation theory,
renormalization group arguments in $4-\epsilon$ dimensions, as well as $1/N$
expansion techniques in 3 dimensions, we argue that the transition from the
high temperature symmetry restoring phase to the low temperature phase is first
order for a range of scalar couplings. This result is not due to gauge
couplings. We discuss the implications of our results for baryogenesis in the
two Higgs-doublet electroweak model, especially when the lightest neutral Higgs
is heavier than the W--bosons.
