M. Gurtler et al., HOT ELECTROWEAK MATTER NEAR TO THE END-POINT OF THE PHASE-TRANSITION, Nuclear physics. B, Proceedings supplement, 63, 1998, pp. 563-565
The electroweak phase transition is investigated near to its endpoint
in the framework of an effective three-dimensional model. We measure t
he very weak interface tension with the tunneling correlation length m
ethod. First results for the mass spectrum and the corresponding wave
functions in the symmetric phase are presented.
