STATIONARY PERTURBATIONS AND INFINITESIMAL ROTATIONS OF STATIC EINSTEIN-YANG-MILLS CONFIGURATIONS WITH BOSONIC MATTER

Using the Kaluza-Klein structure of stationary spacetimes, a famework for analyzing stationary perturbations of static Einstein-Yang-Mills c onfigurations with bosonic matter fields is presented. It is shown tha t the perturbations giving rise to a nonvanishing ADM angular momentum are governed bq a self-adjoint system of equations for a set of gauge -invariant scalar amplitudes. The method is illustrated for SU(2) gaug e fields, coupled to a Higgs doublet or a Higgs triplet. It is argued that slowly rotating black holes arise generically in self-gravitating non-Abelian gauge theories with bosonic matter, whereas, in general, soliton solutions do not have rotating counterparts.
