Abstract

We report the first measurements, with fully dynamical fermions, of the (zero-temperature) chiral symmetry-breaking phase transition in the SU (2) part of the standard SU(2)×U(1) electroweak lattice gauge theory. These are performed with a Langevin algorithm. Good agreement is found with the previous analytic strong gauge coupling results, regarding both the location and the order of the transition. The chiral boundary is also measured in the interior of the phase diagram and the phase structure with dynamical fermions is discussed.
