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...
