Abstract.

We study the non-compact version of the U(1) gauge-Higgs model in three dimensions for \(m_H = 30\) GeV. We found that, using this formulation, rather modest lattices approach quite well the infinite volume behaviour.The phase transition is first order, as expected for this Higgs mass. The latent heat (in units of \(T_{cr}^4\)) is compatible with the predictions of the two-loop effective potential; it is an order of magnitude less than the corresponding SU(2) value. The transition temperature and \(\langle \varphi^* \varphi\rangle \) in units of the critical temperature are also compatible with the perturbative results.
