| 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 = Nf − 1 extra flavours in the fundamental representation. We argue that, even at nf ̸= 0, suitably chosen correlators in this theory can be mapped to those of SYM as N → ∞. We give arguments why this correspondence should be particularly good for Nf = 3 and compare our prediction with available (real and Monte Carlo) data. |
