Search for the $0^{--}$ Glueball in $\Upsilon(1S)$ and $\Upsilon(2S)$   decays
  We report the first search for the $J^{PC}=0^{--}$ glueball in $\Upsilon(1S)$ and $\Upsilon(2S)$ decays with data samples of $(102\pm2)$ million and $(158\pm4)$ million 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 $\Upsilon(1S)$ and $\Upsilon(2S)$ decays are obtained. The inclusive branching fractions of the $\Upsilon(1S)$ and $\Upsilon(2S)$ decays into final states with a $\chi_{c1}$ are measured to be $\BR(\Upsilon(1S)\to \chi_{c1}+ anything) = (1.90\pm 0.43(stat.)\pm 0.14(syst.))\times 10^{-4}$ with an improved precision over prior measurements and $\BR(\Upsilon(2S)\to \chi_{c1}+ anything) = (2.24\pm 0.44(stat.)\pm 0.20(syst.))\times 10^{-4}$ for the first time.
