Improved measurement of branching fractions for ππ transitions among Υ(nS) states

Using samples of (5.93±0.10)×106 Υ(3S) decays and (9.11±0.14)×106 Υ(2S) decays collected with the CLEO detector, we report improved measurements of the following branching fractions: B(Υ(3S)→Υ(1S)π+π-)=(4.46±0.01±0.13)%, B(Υ(2S)→Υ(1S)π+π-)=(18.02±0.02±0.61)%, B(Υ(3S)→Υ(1S)π0π0)=(2.24±0.09±0.11)%, B(...
