Matter near to the endpoint of the electroweak phase transition

Abstract

Wave functions and the screening mass spectrum in the 3 D SU(2)—Higgs model near to the phase transition line below the endpoint and in the crossover region are calculated. In the crossover region the changing spectrum versus temperature is examined showing the aftermath of the phase transition at lower Higgs mass. Large sets of operators with various extensions are used allowing to identify wave functions in position space.
