Abstract

A previous estimate of the quark condensate in one-flavour mass- less QCD from the known value of the gluino condensate in super Yang-Mills (SYM) theory is extended to Nf > 1 by considering the large-N limit of an SU(N) gauge theory with one flavour in the antisymmetric representation and nf...
