EinsteinYangMills solutions in higher dimensional de Sitter spacetime
Abstract
We consider particlelike and black hole solutions of the EinsteinYangMills system with positive cosmological constant in d>4 spacetime dimensions. These configurations are spherically symmetric and present a cosmological horizon for a finite value of the radial coordinate, approaching asymptotically the de Sitter background. In the usual YangMills case, we find that the mass of these solutions, evaluated outside the cosmological horizon at future/past infinity, generically diverges for d>4. Solutions with finite mass are found by adding to the action higher order gauge field terms belonging to the YangMills hierarchy. A discussion of the main properties of these solutions and their differences from those of the usual YangMills model, both in four and higher dimensions, is presented.

A continuum of new monopole and dyon solutions in the EinsteinYangMills theory in asymptotically antide Sitter space are found. They are regular everywhere and specified by their mass and their nonAbelian electric and magnetic charges. A class of monopole solutions which have no node in nonAbelian magnetic fields is shown to be stable against spherically symmetric linear perturbations. (c) 2000 The American Physical Society.

Soliton and black hole solutions of su(N) EinsteinYangMills theory in antide Sitter space
We present new soliton and hairy black hole solutions of su(N) EinsteinYangMills theory in asymptotically antide Sitter space. These solutions are described by N+1 independent parameters, and have N1 gauge field degrees of freedom. We examine the space of solutions in detail for su(3) and su(4) solitons and black holes. If the magnitude of the cosmological constant is sufficiently large, we find solutions where all the gauge field functions have no zeros. These solutions are of particular interest because we anticipate that at least some of them will be linearly stable. 
FaddeevPopovghost propagators for YangMills theories and perturbative quantum gravity in the covariant gauge in de Sitter spacetime
The propagators of the FaddeevPopov (FP) ghosts for YangMills theories and perturbative quantum gravity in the covariant gauge are infrared (IR) divergent in de Sitter spacetime. We point out, however, that the modes responsible for these divergences will not contribute to loop diagrams in computations of timeordered products in either YangMills theories or perturbative quantum gravity. Therefore, we propose that the IRdivergent FPghost propagator should be regularized by a small mass term that is sent to zero in the end of any perturbative calculations. This proposal is equivalent to using the effective FPghost propagators, which we present in an explicitmore » 
Existence of topological hairy dyons and dyonic black holes in antide Sitter su(N) EinsteinYangMills theory
We investigate dyonic black hole and dyon solutions of fourdimensional su(N) EinsteinYangMills theory with a negative cosmological constant. We derive a set of field equations in this case, and prove the existence of nontrivial solutions to these equations for any integer N, with 2N − 2 gauge degrees of freedom. We do this by showing that solutions exist locally at infinity, and at the event horizon for black holes and the origin for solitons. We then prove that we can patch these solutions together regularly into global solutions that can be integrated arbitrarily far into the asymptotic regime. Our mainmore » 
Exact solutions of EinsteinYangMills theory with higherderivative coupling
We construct an exact classical solution of an EinsteinYangMills system in ten spacetime dimensions whose action contains a term quartic in YangMills field strength. The solution provides compactification proposed by Cremmer and Scherk; the tendimensional spacetime with a cosmological constant is compactified to the direct product of fourdimensional Minkowski spacetime and a sixdimensional sphere S{sup 6} whose radius is determined by coupling constants. We also construct a solution which compactifies the tendimensional spacetime to AdS{sub 4}xS{sup 6} when the cosmological constant is absent.
