公開日期: | 2017 | 卷: | 95 | 期: | 1 | 來源出版物: | Physical Review D | 摘要: | We report the first search for the JPC=0 - glueball in (1S) and (2S) 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 (1S) and (2S) decays are obtained. The inclusive branching fractions of the (1S) and (2S) decays into final states with a χc1 are measured to be B( (1S)→χc1+anything)=(1.90±0.43(stat)±0.14(syst))×10-4 with an improved precision over prior measurements and B((2S)→χc1+anything)=(2.24±0.44(stat)±0.20(syst))×10-4 for the first time. ? 2017 American Physical Society. |
