Study of $\Xi^-_b$ and $\Omega^-_b$ decays to $\Lambda_c^+ h^- h^{\prime -}$ final states
/LHCb Collaboration
Decays of $\Xi_b^-$ and $\Omega_b^-$ baryons to $\Lambda_c^+ h^- h^{\prime -}$ final states, with $h^- h^{\prime -}$ being $\pi^-\pi^-$, $K^-\pi^-$ and $K^-K^-$, are searched for using data collected with the LHCb detector. The data sample studied corresponds to an integrated luminosity of $8.7 \,{\rm fb}^{-1}$ of $pp$ collisions collected at centre-of-mass energies $\sqrt{s} = 7$, $8$ and $13 \,{\rm TeV}$. [...]

Simultaneous determination of the CKM angle $\gamma$ and parameters related to mixing and CP violation in the charm sector
/LHCb Collaboration
A combination of measurements sensitive to the $C\!P$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa unitarity triangle, to the charm mixing parameters that describe oscillations between $D^0$ and $\bar{D}^0$ mesons, and to $C\!P$ asymmetries in the $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$ decays is performed. All relevant beauty and charm results obtained with the data collected with the LHCb detector at CERN's Large Hadron Collider to date are included. [...]

Simultaneous determination of CKM angle $\gamma$ and charm mixing parameters
/LHCb Collaboration
A combination of measurements sensitive to the $CP$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa (CKM) unitarity triangle and to the charm mixing parameters that describe oscillations between $D^0$ and $\overline{D}^0$ mesons is performed. Results from the charm and beauty sectors, based on data collected with the LHCb detector at CERN's Large Hadron Collider, are included together for the first time. [...]

Updated LHCb combination of the CKM angle $\gamma$
/LHCb Collaboration
The latest results of the CKM angle $\gamma$ combination are presented for the 2020 LHCb Implications Workshop. New and updated inputs from $B^+ \to Dh^+$ ($D\to h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} K^+ \pi^-$), $B^+ \to D^*h^+$ ($D\to h^+h^-$), $B^0 \to D K^{*0}$ ($D\to h^+h^-$ and $D\to h^+\pi^-\pi^+\pi^-$) and $B^0_s \to D^\mp_s K^\pm \pi^\mp \pi^\pm$ ($D^+_s \to h^+ h^- \pi^+$) decays are included, where $h = K$ or $\pi$.

Combination of the ATLAS, CMS and LHCb results on the $B^0_{(s)} \to \mu^+ \mu^-$ decays
/LHCb Collaboration
A combination of results on the rare $B^0_{s} \to \mu^+ \mu^-$ and $B^0 \to \mu^+ \mu^-$ decays from the ATLAS, CMS, and LHCb experiments using data collected at the Large Hadron Collider between 2011 and 2016, is presented. The $B^0_{s} \to \mu^+ \mu^-$ branching fraction is obtained to be $\left( 2.69\,^{+\, 0.37}_{-\, 0.35} \right) \times 10^{-9}$ and the effective lifetime of the $B^0_{s} \to \mu^+ \mu^-$ decay is measured to be $\tau_{B^0_{s} \to \mu^+ \mu^-} = 1.91^{+0.37}_{-0.35} \rm{ps}$.
