Abstract

We present an analysis of J ψ →γf 1 (1285) , f 1 (1285)→ π + π − π + π − , using the Mark III detector at SPEAR, based on 5.8 × 10 6 produced J ψ events. We measure B( J ψ →γf 1 (1285) , f 1 (1285)→ π + π − π + π − )=(4.8±1.3±0.9) × 10 −5 . We obtain a new measurement of the absolute branching ratio of J ψ →γf 1 (1285) . The mixing angle of the f 1 (1285) and the f 1 (1420) in the 1 ++ nonet is determined.

Abstract

We report a high statistics study of the inclusive decay properties of the charmed D0 and D+ mesons, and the first inclusive study of the charmed Ds+. The data are collected at s =3.77 GeV and s =4.14 GeV with the Mark III detector at the e+e− storage ring SPEAR. For each charmed meson species, the charged-particle multiplicity, the strangeness content of the final state, and the average π0 multiplicity are determined.
