Branes and Theta Dependence

High Energy Physics - Theory 2009-09-29 v1

Abstract

We use the fivebrane of M theory to study the θ\theta dependence of four dimensional SU(Nc)SU(N_c) super Yang-Mills and super QCD softly broken by a gaugino mass. We compute the energy of the vacuum in the supergravity approximation. The results obtained are in qualitative agreement with field theory. We also study the θ\theta dependence of the QCD string tension via the fivebrane.
