Measurement of the mass difference and relative production rate of the $\Omega^-_b$ and $\Xi^-_b$ baryons
/ LHCb Collaboration
The mass difference between the $\Omega^-_b$ and $\Xi^-_b$ baryons is measured using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of $9 \, \textrm{fb}^{-1}$, and is found to be \begin{equation} m(\Omega^-_b)- m(\Xi^-_b) = 248.54 \pm 0.51 \textrm{(stat)} \pm 0.38 \textrm{(syst)} \, \textrm{MeV}/c^2.

Test of lepton flavour universality using $B^0 \to D^{*-}\tau^+\nu_{\tau}$ decays with hadronic $\tau$ channels
/ LHCb Collaboration
The branching fraction $\mathcal{B}(B^0 \to D^{*-}\tau^+\nu_\tau)$ is measured relative to that of the normalisation mode $B^0 \to D^{*-}\pi^+\pi^-\pi^+$ using hadronic $\tau^+ \to \pi^+\pi^-\pi^+(\pi^0)\bar{\nu}_\tau$ decays in proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the LHCb experiment, corresponding to an integrated luminosity of 2 fb$^{-1}$.
