$|V_{cb}|$ and $\gamma$ from $B$-mixing -- Addendum to "$B_s$ mixing observables and $|V_{td}/V_{ts}|$ from sum rules"

Abstract

In this addendum to "$B_s$ mixing observables and $|V_{td}/V_{ts}|$ from sum rules" \cite{King:2019lal} we study the impact of the recent improvements in the theoretical precision of $B$ meson mixing onto CKM unitarity fits. Our key results are the most precise determination of the angle $\gamma ={\left(63.4\pm 0.9\right)}^{\circ }$ in the unitarity triangle and a new value for the CKM element $|V_{cb}|=(41.6\pm 0.7)\cdot 10^{-3}$.
