Query: On the phase transition in the scalar theory   The basic tool for the study of the electroweak phase transition is $V_{eff}
(\phi,T)$, the one-loop finite-temperature effective potential, improved by
all-loop resummations of the most important infrared contributions. In this
paper we perform, as a first step towards a full analysis of the Standard Model
case, a detailed study of the effective potential of the scalar theory. We show
that subleading corrections to the self-energies lead to spurious terms, linear
in the field-dependent mass $m(\phi)$, in the daisy-improved effective
potential. Consistency at subleading order requires the introduction of
superdaisy diagrams, which prevent the appearance of linear terms. The
resulting $V_{eff}(\phi,T)$ for the scalar theory hints at a phase transition
which is either second-order or very weakly first-order.
