Open full text 10 citations
Abstract
Using high precision numerical simulations, the authors investigate the electroweak sphaleron of the standard model in an external (hyper)magnetic field. They find that the electroweak crossover temperature decreases with increasing field strength and the sphaleron rate suppression is shifted to lower temperatures.
