B(s) → ηc(P,V) decays and effects of the next-to-leading order contributions in the perturbative QCD approach
By employing the perturbative QCD (PQCD) factorization approach, we studied the sixteen B/Bs→ηc(π,K,η(′),ρ,K⁎,ω,ϕ) decays with the inclusion of the currently known next-to-leading order (NLO) contributions. We found the following main points: (a) for the five measured B→ηc(K,K⁎) and Bs→ηcϕ decays, t...
