The production ofJ/ψ inB meson decays has been measured on the Γ(4S) resonance using the Crystal Ball detector at thee+e− storage ring DORIS II. TheJ/ψ is identified by itse+e− decay mode. We obtain a branching ratio of BR(B→J/ψX)=(1.12±0.

Charged hadron production ine+e− annihilation is studied in the 7 to 10 GeV CM energy region and at the Υ (9.46) and Υ′ (10.01) resonances with the LENA detector at DORIS. The statistical moments of the charged multiplicities are studied. The d
