Is the BELLE result for the cross section e+e- -> J/psi+eta_c a real difficulty for QCD ?
read the original abstract
It is shown that difficulties in reconciling the values of the cross section e+e- -> J/psi+eta_c measured at BELLE and calculated within non-relativistic QCD (NRQCD) are caused not by some misinterpretation of the data or other exotic explanations, but by poor applicability of NRQCD to such processes. We use general theory of hard exclusive processes in QCD together with more realistic models of charmonium wave functions, and show that the BELLE result can be naturally explained.

Analytical two-loop amplitudes of $e^{+} e^{-} \longrightarrow \boldsymbol{J} / \boldsymbol{\psi}+\boldsymbol{\eta}_c$ at $B$ factories
The authors present the first analytical two-loop NRQCD amplitude for e+e- to J/psi+eta_c as an expansion in m_c^2/s, with cross-section predictions consistent (within uncertainties) with B-factory data.

Radiative Decays of Vector Mesons with Light-Cone Sum Rules
Light-cone sum rules yield radiative decay widths for ground-state vector mesons that match data where available and exhibit a universal linear dependence on a function A(x) in log coordinates arising from decay-const...

Radiative Decays of Vector Mesons with Light-Cone Sum Rules
LCSR calculations give M1 radiative widths for K*, D*, B*, D_s*, B_s*, and ψ(2S), matching K* data and yielding a fitted universal log-log scaling with A(2.1).
