Indications of the possible observation of the lowest-lying 1-+ QCD state

We discuss properties of 1(-+) exotic mesons within the framework of the QCD field-theoretic approach. We estimate the mass of the lowest-lying 1(-+) exotic meson using renormalization-improved QCD sum rules, and find that the mass lies around 1.26 +/- 0.15 GeV, in good agreement with the pi(1)(1400) data. This state should be expected in QCD. We find that the mass for the lowest-lying strange 1(-+) meson is 1.31 +/- 0.19 GeV. Our result hints that the K*(1410) may be the lowest-lying 1(-+) nonet state.
