Constraints on hard spectator scattering and annihilation corrections in $B_{u, d}$ $\to$ $P V$ decays within QCD factorization

Junfeng Sun, Qin Chang, Xiaohui Hu +1

In this paper, we investigate the contributions of hard spectator scattering and annihilation in $B \to P V$ decays within the QCD factorization framework. With available experimenta…

B\to K_1π(K) decays in the perturbative QCD approach

Zhi-Qing Zhang, Zhi-Wei Hou, Yueling Yang +1

Within the framework of the perturbative QCD approach, we study the two-body charmless decays $B \to K_{1} (1270) (K_{1} (1400)) π (K)$ . We find the following results: (i) The decays $\bar B…

Spectator Scattering and Annihilation Contributions as a Solution to the $π K$ and $π π$ Puzzles within QCD Factorization Approach

Qin Chang, Junfeng Sun, Yueling Yang +1

The large branching ratios for pure annihilation $B ˉ_{s}^{0}$ $\to$ $π^{+} π^{-}$ and $B ˉ_{d}^{0}$ $\to$ $K^{+} K^{-}$ decays reported by CDF and LHCb collaborations recently and the so-…

A Combined Fit on the Annihilation Corrections in $B_{u, d, s}$ $\to$ $P P$ Decays Within QCDF

Qin Chang, Junfeng Sun, Yueling Yang +1

Motivated by the possible large annihilation contributions implied by recent CDF and LHCb measurements on nonleptonic annihilation B meson decays, and the refined experimental meas…

Study of the $B_{c}$ $\to$ $B_{s} π$ decay with the perturbative QCD approach

Junfeng Sun, Yueling Yang, Gongru Lu

The $B_{c}$ $\to$ $B_{s} π$ decay is studied with the perturbative QCD approach. Three types of wave functions for $B_{s}$ meson are considered. The transition form factor $F_{0}^…

Phenomenological study of the $B_{c}$ $\to$ $B P$ , $B V$ decays with perturbative QCD approach

Junfeng Sun, Yueling Yang, Qin Chang +1

Inspired by the recent LHCb measurements and forthcoming great potential on $B_{c}$ meson, we study the exclusive $B_{c}$ $\to$ $B_{q} P$ , $B_{q} V$ decays with the perturbative QC…
