abstract
We discuss the impact of the recent $\mathcal{O}(\alpha_s^3)$ calculations of the semileptonic width of the $b$ quark and of the relation between pole and kinetic heavy quark masses by Fael et al. on the inclusive determination of $|V_{cb}|$. The most notable effect is a reduction of the uncertainty. Our final result is $|V_{cb}|=42.16(51)\, 10^{-3}$.

Standard Model tests with smeared experiment and theory
Finite-width Poisson smearing of both experiment and lattice theory permits model-independent Standard Model comparisons for inclusive semileptonic decays and for interference observables in rare semileptonic decays, ...

New Physics in inclusive semileptonic $B$ decays
A global fit to inclusive semileptonic B decay moments and rate constrains all seven dimension-six new-physics parameters, finding no significant BSM signal but new bounds, especially on the right-handed vector Wilson...

Current-current operator contribution to the decay matrix in $B$-meson mixing at next-to-next-to-leading order of QCD
The full charm-mass dependence of the three-loop current-current contribution to the B-meson decay matrix is computed, yielding Delta_Gamma_s = (0.077 +/- 0.016) ps^-1 with the leading-term perturbative error reduced ...

Weak decays of $B_s$ meson in self-consistent covariant light-front approach
A self-consistent light-front quark model calculation gives B_s to P(V) form factors and decay observables, with semileptonic results consistent with lattice QCD and LHCb but nonleptonic predictions requiring fitted e...
