Systematic analysis of the form factors of Bc → ηc, J/ψ and corresponding weak decays
The form factors of Bc→ηc and Bc→J/ψ are analyzed in the framework of three-point QCD sum rules. In the calculations, the contributions of the vacuum condensate terms 〈gs2GG〉 and 〈gs3GGGf〉 are considered. In addition, the decay widths and branching ratios of several decay channels are predicted by u...
