Sphaleron in the Dilatonic Gauge Field Theory

Abstract

Motivated by the Kaluza-Klein theory with a large number of extra spacetime dimensions, we present a numerical study of static, spherically symmetric sphaleron solutions coupled to the dilaton fields. We show that sphalerons may have different dilaton cloud configurations, resulting in new massive sphalerons, in general. However, there exist different cloud configurations with different values of the dilaton mass.
