Description:
Author(s): S. D. Yang et al. (Belle Collaboration) Using data samples of 102×10 6 ϒ(1S) and 158×10 6 ϒ(2S) events collected with the Belle detector, a first experimental search has been made for double-charmonium production in the exclusive decays ϒ(1S,2S)→J/ψ(ψ ′ )+X, where X=η c , χ cJ (J=0,1,2), η c (2S), X(3940), and X(4160). No significant signal is obse... [Phys. Rev. D 90, 112008] Published Tue Dec 16, 2014
