Precise theoretical prediction on branching fractions and polarizations of $D \to V V$ decays

Jing Ou-Yang, Hui Zheng, Run-Hui Li +1

We present a precise and systematic analysis of $D \to V V$ decays within the factorization-assisted topological-amplitude approach, where $D$ denotes the set $\{D^0, \, D^+,\, D^+…

Meson-baryon scattering lengths without annihilation diagrams to order $p^{4}$ in heavy baryon chiral perturbation theory

Jing Ou-Yang, Ke Wang, Bo-Lin Huang

We calculate the threshold $T$ matrices of the meson and baryon processes that have no annihilation diagrams: $I ¨ ^{+} I^£^{+}$ , $I ¨ ^{+} I^^{0}$ , $K^{+} p$ , $K^{+} n$ , and $K ˉ^{0} I^^{0}$ to t…

Analysis of three-body charmed $B$ meson decays $B \to D (V^{*} \to) V P$

Jing Ou-Yang, Run-Hui Li, Si-Hong Zhou

We systematically analyze the decays $B_{(s)} \to D_{(s)} (V^{*} \to) V P$ , where $V^{*}$ represents a vector resonance ( $I ¨ , I ¨ $ or $K^{*}$ ), and $V P$ denotes the final-state me…

Pion-nucleon scattering with decuplet contribution in heavy baryon SU(3) chiral perturbation theory

Jing Ou-Yang, Bo-Lin Huang

We calculate the complete $T$ matrices with decuplet contributions for pion-nucleon scattering to order $O (I^µ^{3})$ in heavy baryon SU(3) chiral perturbation theory. The ba…
