Abstract
We present a study of the inclusive D[superscript * ±] production in the decay of Υ(1S) using (98.6±0.9)×10[superscript 6] Υ(2S) mesons collected with the BABAR detector at the Υ(2S) resonance. Using the decay chain Υ(2S)→π[superscript +] π[superscript -] Υ(1S), Υ(1S)→D[superscript * ± ]X, where X is unobserved, we measure the branching fraction B[Υ(1S)→D* ± X]=(2. 52±0.13(stat)±0.15(syst))% and the D* ± momentum distribution in the rest frame of the Υ(1S). We find evidence for an excess of D[superscript * ±] production over the expected rate from the virtual photon annihilation process Υ(1S)→γ *→cc̄→D[superscript * ± ]X.
