A J^PG=1++ Charged Resonance in the Y(4260) to pi+pi- J/psi Decay?

Abstract

New BES and Belle data show a peak in the Y(4260) decay into J/psi plus one charged pion. We point out that the peak might correspond to a charged resonance at about 3880 MeV predicted time ago within a tetraquark model. The same tetraquark model predicts another peak at about 100 MeV below the observed one. We discuss the possibility of having it in present data. On the other hand we expect that if the molecular picture were the correct one, a peak corresponding to a D* D*bar state should appear at about 4020 MeV.
