چکیده
In this paper we investigate the possibility of studying B → π form factor using the semi-inclusive decays ¯ B 0 → π + + X q. In general B → P X semi-inclusive decays involve several hadronic parameters. But for ¯ B 0 → π + X q decays we find that in the factorization approximation, the only unknown hadronic parameters are the form factors F B→π 0,1. Therefore these form factors can be studied in ¯ B 0 → π + X q decays. Using theoretical model calculations for the form factors the branching ratios for ¯

By fitting the R values between 3.7 and 5.0 GeV measured by the BES collaboration, the upper limit of the electron width of the newly discovered resonance Y (4260) is determined to be 580 eV/c 2 at 90% C.L. Together with the BaBar measurement on Γee·B(Y (4260) → π + π − J/ψ), this implies a large decay width of Y (4260) → π + π − J/ψ final states.
