Bayesian Extraction of HQET Parameters from Inclusive Semi-Leptonic Decay of the $I^_{c}^{+}$ Baryon

Kangkang Shao, Dong Xiao

We extract the non-perturbative Heavy Quark Effective Theory (HQET) parameters from the inclusive semi-leptonic decay $I^_{c}^{+} \to X e^{+} I^½_{e}$ . Unlike charmed mesons produced near t…

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 $D^{0}, D^{+}, D_{s}^{+} \to X e^{+} I^½$ . The theoretical formulas for the decay widths and…
