Temperature Induced Phase Transitions and Stable Vacuum for Electroweak Interactions in Magnetic Field

摘要

In the electroweak interactions theory the temperature induced phase transitions in a magnetic field H being defined from the numerical investigations of the one-loop thermodynamical potential have been considered. A new vacuum phase conditioned by the action of both field H and temperature T is found. All the possible vacuum structures, being stale at H, T not equal to 0, are discribed and it is shown that the character of both phase transition and structure appeared in vacuum are uniquely defined by the ratio sqrt K=m/M the Higgs and the W-boson masses. 32 refs.; 4 figs.
