Mass spectrum of the 3d SU(2) Higgs model and the symmetric electroweak phase

Abstract We present results for the masses of the low-lying states with quantum numbers 0 ++ , 2 ++ and 1 −− as well as Polyakov line correlations in the Higgs and confinement regions of the 3d SU(2) Higgs model. In the confinement phase we find a dense spectrum of bound states approximately split into two disjoint sectors. One consists of W-balls nearly identical to the glueball spectrum of the pure gauge theory, the other of bound states of scalars.
