The decays B→Ψ(2S)π(K),ηc(2S)π(K) in the pQCD approach beyond the leading-order
Two body B meson decays involving the radially excited meson ψ(2S)/ηc(2S) in the final states are studied by using the perturbative QCD (pQCD) approach. We find that: (a) The branching ratios for the decays involving a K meson are predicted as Br(B+→ψ(2S)K+)=(5.37−2.22+1.85)×10−4, Br(B0→ψ(2S)K0)=(4....
