QCD calculations of radiative heavy meson decays with subleading power corrections

Hua-Dong Li, Cai-Dian Lü, Chao Wang +2

We revisit QCD calculations of radiative heavy meson decay form factors by including the subleading power corrections from the twist-two photon distribution amplitude at next-to-le…

Revisit to the $b \to c τ ν$ transition: in and beyond the SM

Kingman Cheung, Zhuo-Ran Huang, Hua-Dong Li +3

We perform an analysis of the $b \to c τ ν$ data, including $R (D^{(*)})$ , $R (J / ψ)$ , $P_{τ} (D^{*})$ and $F_{L}^{D^{*}}$ , within and beyond the Standard Model (SM). We fit the $B \to D^{(*)}$ …

$D^{} D ρ$ and $B^{} B ρ$ strong couplings in light-cone sum rules

Chao Wang, Hua-dong Li

We present an improved calculation of the strong coupling constants $g_{D^{*} D ρ}$ and $g_{B^{*} B ρ}$ in light-cone sum rules including the one-loop QCD corrections of leading power with…
