Radiative first-order phase transitions to next-to-next-to-leading order


Andreas Ekstedt



We develop new perturbative tools to accurately study radiatively induced first-order phase transitions. Previous perturbative methods have suffered internal inconsistencies and been unsuccessful in reproducing lattice data, which is often attributed to infrared divergences of massless modes (the Linde problem). We employ a consistent power counting scheme to perform calculations and compare our results against lattice data. We conclude that the consistent expansion removes many previous issues and indicates that the infamous Linde problem is not as big a factor in these calculations as previously thought.
