SUSY Relics in Ordinary QCD

Recent work by Armoni, Shifman and Veneziano suggests that in the large N-color limit, N=1 Supersymmetric Yang-Mills Theory (SYM) is equivalent to 1-flavor QCD. In this proposed equivalence the massless gluino sparticle in the adjoint representation of SYM becomes a quark in the antisymmetric representation of 1-flavor QCD, while the gauge field and gauge couplings remain unchanged. One consequence of such an equivalence is that the scalar and pseudoscalar mesons of 1-flavor QCD should have degenerate mass, since they originate within the same Wess-Zumino supermultiplet of SYM. We use previously published lattice results to compare the masses of scalar and pseudoscalar mesons in 1-flavor QCD. We also perform a similar flavor singlet meson mass comparison in the CP(3) model.
