Abstract

We study transitions between Υ states with the emission of charged pions using 477fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured product branching fraction B(Υ(4S)→Υ(1S)π+π-)×B(Υ(1S)→μ+μ-)=(4. 42±0.81(stat)±0.56(sys))×10-6. When the PDG value for B(Υ(1S)→μ+μ-) is used, this corresponds to B(Υ(4S) →Υ(1S)π+π-)=(1.78±0.33(stat)±0.23(sys)) ×10-4 and a partial decay width Γ(Υ(4S)→Υ(1S) π+π-)=(3.65±0.67(stat)±0.65(sys))keV.
