dc.description.abstract | We calculate the branching ratio for the production of the meson Y(4260) in the decay B<sup>-</sup>→Y(4260)K<sup>-</sup>. We use QCD sum rules approach and we consider the Y(4260) to be a mixture between charmonium and exotic tetraquark, [cq][qc], states with J<sup>PC</sup>=1<sup>--</sup>. Using the value of the mixing angle determined previously as: θ=(53.0±0.5)°, we get the branching ratio B(B→Y(4260)K)=(1.34±0.47)×10-6, which allows us to estimate an interval on the branching fraction 3.0×10-8<BY<1.8×10-6 in agreement with the experimental upper limit reported by BaBar Collaboration. | en |
