dc.description.abstract | We search for the J(PC) = 0(--) and 1(+-) light tetraquark states with masses up to 2.46 GeV/c(2) in gamma(1S) and gamma(2S) decays with data samples of (102 +/- 2) million and (158 +/- 4) million events, respectively, collected with the Belle detector. No significant signals are observed in any of the studied production modes, and 90% credibility level (C. L.) upper limits on their branching fractions in Upsilon(1S) and Upsilon(2S) decays are obtained. The inclusive branching fractions of the Upsilon(1S) and Upsilon(2S) decays into final states with f(1)(1285) are measured to be B(Upsilon(1S) -> f(1)(1285) + anything) = (46 +/- 28(stat) +/- 13(syst)) x 10(-4) and B(Upsilon(2S) -> f(1)(1285) + anything) = (22 +/- 15(stat) +/- 6.3(syst)) x 10(-4). The measured chi(b2) -> J/Psi + anything branching fraction is measured to be (1.50 +/- 0.34(stat) +/- 0.22(syst)) x 10(-3), and 90% C. L. upper limits for the chi(b0;b1) -> J/Psi + anything branching fractions are found to be 2.3 x 10(-3) and 1.1 x 10(-3), respectively. For B(chi(b1) -> omega + anything), the branching fraction is measured to be (4.9 +/- 1.3(stat) +/- 0.6(syst) x 10(-2). All results reported here are the first measurements for these modes. | en_US |
