Measurement of Inclusive Production of Neutral Pions from Upsilon(4S) Decays
Belle Collaboration, K. Abe
Abstract
Using the Belle detector operating at the KEKB e+e- storage ring, we have measured the mean multiplicity and the momentum spectrum of neutral pions from the decays of the Upsilon(4S) resonance. We measure a mean of 4.70 +/- 0.04 +/- 0.22 neutral pions per Upsilon(4S) decay.
