Abstract

We analyze a correlation function of two currents with quark exotic quantum numbers J^PC = 1^-+, I^G = 0⁺ and 1^-, following the technique of the ITEP group. With non-perturbative effects taken into account phenomenologically, we conclude that a strong peak should manifest itself in the spectral density of this correlation function at E ≈ 1 GeV, which should be interpreted as a quark-antiquark-gluon resonance.
