Abstract

The branching fractions of the $��(1S)$ inclusive decays into final states with a $J/��$ or a $��(2S)$ are measured with improved precision to be $\BR(��(1S)\to J/��+ {\rm anything})=(5.25\pm 0.13(\mathrm{stat.})\pm 0.25(\mathrm{syst.}))\times 10^{-4}$ and $\BR(��(1S)\to ��(2S) + {\rm anything})=(1.23\pm 0.17(\mathrm{stat.})\pm 0.11(\mathrm{syst.}))\times 10^{-4}$. The first search for $��(1S)$ decays into $XYZ$ states that decay into a $J/��$ or a $��(2S)$ plus one or two charged tracks yields no significant signals for $XYZ$ states in any of the examined decay modes, and upper limits on their production rates in $��(1S)$ inclusive decays are determined., 10 pages, 7 figures, 3 tables

Abstract

Using data samples of $102\times10^6$ $��(1S)$ and $158\times10^6$ $��(2S)$ events collected with the Belle detector, a first experimental search has been made for double-charmonium production in the exclusive decays $��(1S,2S)\rightarrow J/��(��')+X$, where $X=��_c$, $��_{cJ} (J=~0,~1,~2)$, $��_c(2S)$, $X(3940)$, and $X(4160)$. No significant signal is observed in the spectra of the mass recoiling against the reconstructed $J/��$ or $��'$ except for the evidence of $��_{c1}$ production with a significance of $4.6��$ for $��(1S)\rightarrow J/��+��_{c1}$. The measured branching fraction $\BR(��(1S)\rightarrow J/��+��_{c1})$ is $(3.90\pm1.21(\rm stat.)\pm0.23 (\rm syst.))\times10^{-6}$. The $90\%$ confidence level upper limits on the branching fractions of the other modes having a significance of less than $3��$ are determined. These results are consistent with theoretical calculations using the nonrelativistic QCD factorization approach., 12 pages, 4 figures, 1 table. The fit range was extended to include X(4160) signal according to referee's suggestions. Other results unchanged. Paper was accepted for publication as a regular article in Physical Review D

Abstract

Using data samples of 102 x 10(6) gamma(1S) and 158 x 10(6) gamma(2S) events collected with the Belle detector, a first experimental search has been made for double-charmonium production in the exclusive decays gamma(1S, 2S) --> J/psi(psi') + X, where X = eta(c).chi(cJ) (J = 0, 1, 2), eta(c)(2S), X(3940), and X(4160). No significant signal is observed in the spectra of the mass recoiling against the reconstructed J/psi or psi' except for the evidence of chi(c1) production with a significance of 4.6 sigma for gamma(1S) -> J/psi + chi(c1). The measured branching fraction B(gamma(1S) -> J/psi + chi(c1)) is [3.90 +/- 1.21 (stat) +/- 0.23(syst) x 10(-6). The 90% C.L. upper limits on the branching fractions of the other modes having a significance of less than 3 sigma are determined. These results are consistent with theoretical calculations using the nonrelativistic QCD factorization approach.

Abstract

The branching fractions of the Upsilon(1S) inclusive decays into final states with a J/psi or psi(2S) are measured with improved precision to be B Upsilon(1S) -> J/psi + anything = (5.25 +/- 0.13(stat) +/- 0.25(syst) x 10(-4) and B Upsilon(1S) -> psi(2S) + anything = (1.23 +/- 0.17(stat) +/- 0.11(syst)) x 10(-4). The first search for Upsilon(1S) decays into XYZ states that decay into a J/psi or a psi(2S) plus one or two charged tracks yields no significant signals for XYZ states in any of the examined decay modes, and upper limits on their production rates in Upsilon(1S) inclusive decays are determined.
