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 ${\alpha }_S(m_c^2)$, the strong coupling constant at the charm quark mass $m_c$ with data on inclusive semil…
