Euclidean solutions in Einstein-Yang-Mills-dilaton theory

摘要

We present arguments for the existence of a new type of solutions of the Euclidean Einstein-Yang-Mills-dilaton theory in d = 4 dimensions. Possessing non-vanishing non-Abelian charges, these non-selfdual configurations have no counterparts on the Lorentzian section. They provide, however, new saddle points in the Euclidean path integral. (c) 2006 Elsevier B.V. All rights reserved.
