QCD corrections to e^+ e^- to J/ψ(ψ(2S))+χ_{cJ} (J=0,1,2) at B Factories

Kai Wang, Yan-Qing Ma, Kuang-Ta Chao

We analytically calculate the cross sections of double charmonium production in $e^{+} e^{-} \to J / ψ (ψ (2 S)) χ_{c J}$ (J=0,1,2) at next-to-leading order (NLO) in $α_{s}$ in nonrelativistic…

$χ_{c J}$ production associated with a $c c ˉ$ pair at hadron colliders

Dan Li, Yan-Qing Ma, Kuang-Ta Chao

$χ_{c J}$ (J=0,1,2) production associated with a charm quark pair in hadron collisions is calculated in the framework of nonrelativistic QCD at the Tevatron and LHC. It is found tha…

$O (α_{s} v^{2})$ Corrections to Hadronic and Electromagnetic Decays of $^{1} S_{0}$ Heavy Quarkonium

Huai-Ke Guo, Yan-Qing Ma, Kuang-Ta Chao

We study $O (α_{s} v^{2})$ corrections to decays of $^{1} S_{0}$ heavy quarkonium into light hadrons and two photons within the framework of nonrelativistic QCD, and find these $O (α_{s} v^{2})$ co…
