In supersymmetric gluodynamics (N = 1 super-Yang-Mills theory), we show that the spectral functions induced by the nonchiral operator Tr(G αβλ2) are fully degenerate in the J PC = 1±- channels. The above operator is related to N = 1/2 generalization of SUSY. Using the planar equivalence, this translates into the statement of degeneracy between the mesons produced from the vacuum by the operators (Ψ E→ Ψ + iΨ B→ γ5 Ψ) and (Ψ B→ Ψ - iΨ E → γ5 Ψ) in one-flavor QCD, up to 1/N corrections. Here Ψ is the quark field, and E→, B → are chromoelectric/chromomagnetic fields, respectively.
