We report the first search for the JPC= 0-- glueball in Yð1SÞ and Y=ð2SÞ decays with data samples of (102 ± 2) × 106 and (158 ± 4) × 106 events, respectively, collected with the Belle detector. No significant signals are observed in any of the proposed production modes, and the 90% credibility level upper limits on their branching fractions in Y(1S) andY(2S) decays are obtained. The inclusive branching fractions of the Y(1S) and Y(2S) decays into final states with a χc1 are measured to be B(Y(1S) → χc1 þ anything = (1.90± 0.43(stat) ± 0.14(syst)) × 10-4 with an improved precision over prior measurements and → χc1 + anything) = (2.24 ±0.44(stat) 0.20(syst)) × 10-4 for the first time.
