Exact meron black holes in four dimensional SU(2) Einstein-Yang-Mills theory

Mostrar todas las versiones(3)

In this Letter an intrinsically non-Abelian black hole solution for the SU(2) Einstein-Yang-Mills theory in four dimensions is constructed. The gauge field of this solution has the form of a meron whereas the metric is the one of a Reissner-Nordström black hole in which, however, the coefficient of...

In this Letter an intrinsically non-Abelian black hole solution for the SU(2) Einstein-Yang-Mills theory in four dimensions is constructed. The gauge field of this solution has the form of a meron whereas the metric is the one of a Reissner-Nordström black hole in which, however, the coefficient of the 1/r2 term is not an integration constant.

A remarkable consequence of this fact, which allows to distinguish the present solution from essentially Abelian configurations, is the Jackiw-Rebbi-Hasenfratz-'t Hooft mechanism according to which excitations of Bosonic fields moving in the background of a gauge field with this characteristic behave as Fermionic degrees of freedom. © 2013 Elsevier B.V.
