Determination of Strong Coupling Constant from Inclusive Semileptonic Decays of Charmed Mesons

Jinfei Wu, Xinchou Lou, Yuzhi Che +4

Employing the heavy quark expansion model with the kinetic scheme, we evaluate $\hat{I}{\pm }_S(m_c^2)$, the strong coupling constant at the charm quark mass $m_c$ with data on inclusive semi…
