Determination of the Strong Coupling Constant ${\alpha }_s$ from Inclusive Semi-leptonic $B$ Meson Decays

Yuzhi Che, Long Chen, Jinfei Wu +5

We demonstrate the feasibility of determining the strong coupling constant, ${\alpha }_s$, from the inclusive semileptonic decay width of $B$ mesons. We express the semileptonic $B$ decay…
