Abstract

We discuss the 2-point-particle-irreducible (2PPI) expansion, which sums bubble graphs to all orders, in the context of SU(N) Yang-Mills theory in the Landau gauge. Using the method we investigate the possible existence of a gluon condensate of mass dimension two, 〈A<inf>μ</inf>^aA<inf>μ</inf>^a〉, and the corresponding non-zero vacuum energy. This condensate gives rise to a dynamically generated mass for the gluon. © 2003 Published by Elsevier Science B.V.
