Experimental results for moments of the leptonic $q^2$-spectrum in inclusive semileptonic B-meson decays often involve cuts on $q^2$. Therefore, the spectrum itself (rather than its moments only) needs to be evaluated on the theoretical side. We present results of our calculation of $\mathcal{O}(\alpha_s^2)$ corrections to this spectrum that have been obtained via a numerical solution to...
We present a new global fit for inclusive $V_{cb}$ decays based on the Kolya open-source library, utilizing the full available set of spectral moments of semileptonic $B\to X_c \ell \nu$ decays with state-of-the-art precision. Our approach includes a novel prescription to estimate the uncertainty arising from missing higher-order contributions of order $1/m_b^4$ in the heavy quark expansion...
We report on the progress in the nonperturbative calculation of the decay rate for inclusive semileptonic decays of charmed and bottomed mesons. We provide an overview on the formalism used to reconstruct the inclusive rate and address the ongoing analysis into understanding the systematic errors associated with the analysis, focusing on the error due to the approximation and finite-volume...
