Complete $\mathcal{O}(\hat{I}{\pm }_s^2)$ Corrections to the Leptonic Invariant Mass Spectrum in $b\to X_{c}l\bar{\hat{I}}{½}_l$ Decay

Mateusz Czaja, Mikołaj Misiak, Abdur Rehman

In the determination of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ from inclusive semileptonic $B$-meson decays, moments of the leptonic invariant mass spectrum consti…
