Quasi-two-body decays $B_{c}^{+} \to χ_{c 0, c 1} [ρ (K^{*}) \to] π π (K π)$ in the PQCD approach

Jun Deng, Xian-Qiao Yu

We study the quasi-two-body decays $B_{c}^{+} \to χ_{c 0, c 1} [ρ (K^{*}) \to] π^{+} π^{0} (K^{0} π^{+})$ in the perturbative QCD framework at leading order. The $π π$ and $K π$ pairs are produced via th…

Study of the four-body decays $B_{S}^{0} \to π π π π$ in the perturbative QCD approach

Hui-Qin Liang, Xian-Qiao Yu

In this work, we analyse the CP-averaged branching ratios and direct CP-violating asymmetries of the four-body decays B_{S} \rightarrow ππππdecay from the S-wave resonances, f_{0}(…

The perturbative QCD predictions for the decay B^{0}_{s}\rightarrow SS(a_{0}(980),f_{0}(980),f_{0}(500))

Ze-Rui Liang, Xian-Qiao Yu

In this work, we calculate the branching ratios and CP violations of the B^{0}_{s}\rightarrow a_{0}(980)a_{0}(980) decay modes with both charged and neutral a_{0}(980) mesons and B…

Study of the quasi-two-body decays B^{0}_{s} \rightarrow ψ(3770)(ψ(3686))π^+π^- with perturbative QCD approach

Ze-Rui Liang, Feng-Bo Duan, Xian-Qiao Yu

In this note, we study the contributions from the S-wave resonances, f_{0}(980) and f_{0}(1500), to the B^{0}_{s}\rightarrow ψ(3770)π^ {+}π^{-} decay by introducing the S-wave ππdi…

Study of $B_{s} \to π ρ$ decays in the perturbative QCD approach

Xian-Qiao Yu, Ying Li, Cai-Dian Lü

In this note, we calculate the branching ratio and CP asymmetry parameters of $B_{s} \to π ρ$ in the framework of perturbative QCD approach based on $k_{T}$ factorization. This decay can…

Branching ratio and CP asymmetry of $B_{s} \to π^{+} π^{-}$ decays in the perturbative QCD approach

Ying Li, Cai-Dian Lu, Zhen-Jun Xiao +1

In this paper, we calculate the decay rate and CP asymmetry of the $B_{s} \to π^{+} π^{-}$ decay in perturbative QCD approach with Sudakov resummation. Since none of the quarks in final s…
