Insights into the nature of the $X (3872)$ through B meson decays

Zhi-Qing Zhang, Zhi-Lin Guan, Yan-Chao Zhao +4

We study the decays $B_{c, u, d} \to X (3872) P$ in the perturbative QCD (PQCD) approach, where the puzzling resonance $X (3872)$ is involved and $P$ represents a light pseudoscalar meso…

Quasi-two-body decays $B_{(s)} \to K^{*} γ \to K π γ$ in perturbative QCD approach

Zhi-Qing Zhang, Yan-Chao Zhao, Zhi-Lin Guan +3

In this work we study the quasi-two-body decays $B \to K^{*} γ \to K π γ$ in the perturbative QCD (PQCD) approach. The two-meson distribution amplitudes (DAs) are introduced to describe t…
