Strong constraints on the $K^0_s \to \mu^+ \mu^-$ branching fraction
/LHCb Collaboration
A search for the decay $K^0_s \to \mu^+ \mu^-$ is performed using proton-proton collision data, corresponding to an integrated luminosity of $5.6 \, \text {fb}^{-1}$, collected with the LHCb experiment during 2016, 2017 and 2018 at a center-of-mass energy of $13\,\mathrm{TeV}$. The observed number of signal decays is consistent with zero, yielding an upper limit of $\mathcal {B}( K^0_s \to \mu^+ \mu^-) < 2.2\,(2.6)\times 10^{-10}$ at $90$ $(95)\% ~\text {CL}$ [...]

Search for time-dependent $CP$ violation in $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$ decays
/LHCb Collaboration
A search for charge-parity ($CP$) violation in the time-dependent decay rates of $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$ decays is reported. The data correspond to an integrated luminosity of $1.9\,{\rm fb}^{-1}$ collected by the LHCb detector in 2015--2016 in $pp$ collisions at a centre-of-mass energy of $13\,{\rm TeV}$ [...]

Prospects for searches for long-lived particles after the LHCb detector upgrades
/LHCb Collaboration
The LHCb detector is a single-arm forward spectrometer covering the pseudorapidity range $2 < \eta < 5$, initially designed for the study of particles containing $b$ or $c$ quarks. As such, it is naturally suited for the search of beyond SM long-lived particles in a range of mass and lifetime not too dissimilar to heavy-flavour hadrons, as it has been demonstrated in several publications [...]

LHCb projections for proton-lead collisions during LHC Runs 3 and 4
/LHCb Collaboration
Projected sensitivities for selected LHCb measurements using proton-lead collisions during LHC Runs 3 and 4 are presented. The observables considered are Drell-Yan production with dimuon masses between 5 and 120 $GeV/c^2$ , correlations in the production of $D$ and $\overline D$ mesons, and the nuclear modification factor of $B^+$ meson production [...]

Update of the LHCb combination of the CKM angle $\gamma$
/LHCb Collaboration
A combination of tree-level measurements of the CKM angle $\gamma$ at LHCb is performed. The results are obtained from time-integrated measurements of $B^{+}\to D K^{+}$, $B^{+}\to D^{*}K^{+}$, $B^{+}\to DK^{*+}$, $B^{0}\to D K^{*0}$, $B^{0}\to D K^{+}\pi^{-}$ and $B^{+}\to DK^{+}\pi^{+}\pi^{-}$ decays and time-dependent analyses of $B_{s}^{0}\to D_{s}^{\mp}K^{\pm}$ and $B^{0}\to D^{\mp}\pi^{\pm}$ decays. [...]
