Study of $Λ_{b}^{0} \to Λ D$ decays with the rescattering mechanism

Na Li, Hui-Qiang Shang, Qin Qin

We employ the final-state rescattering mechanism to systematically investigate the non-leptonic decays $Λ_{b}^{0} \to Λ D$ (where $D = D^{0}$ , $D^{0}$ , $D_{+}$ , $D_{-}$ ), which can h…

First determination of $V_{cs, c d}$ from inclusive $D$ meson decays

Kang-Kang Shao, Hai-Long Feng, Xue-Yin Liu +3

We report the first determination of the Cabibbo-Kobayashi-Maskawa matrix elements $∣ V_{cs} ∣$ and $∣ V_{c d} ∣$ from a global fit to data from inclusive and sum-of-exclusive charm dec…

Data determination of HQET parameters in inclusive charm decays

Kang-Kang Shao, Chun Huang, Qin Qin

This work delves into the phenomenology of electronic inclusive decays of $D$ mesons, encompassing $D^{0}, D^{+}, D_{s}^{+} \to X e^{+} ν$ . The theoretical formulas for the decay widths and e…
