Observation of the $X (2370)$ in $J / ψ \to γ K_{S}^{0} K_{S}^{0} π^{0}$ and $J / ψ \to γ π^{0} π^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +769

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, the $J / ψ \to γ K_{S}^{0} K_{S}^{0} π^{0}$ and $J / ψ \to γ π^{0} π^{0} η$ processes are stu…

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…
