Vacuum Phase Transitions and the Temperature of the Universe
Vacuum Phase Transitions and the Temperature of the Universe
The authors discuss a possibility that the present great value of aT ( a is the radius of spatial curvature and T is the temperature of the Universe ) was generated by first order vacuum phase transitions. In Coleman-Weinberg type models such transitions are natural and they rise the value of aT from unity to an exponentially large value. Some GUTs are briefly discussed in this contest.
