Amplitude analysis of the radiative decay $B^0_s\to K^+K^-\gamma$ / LHCb Collaboration
A search for radiative decay of $B^0_s$ mesons to orbitally excited $K^+K^-$ states is performed using proton proton collisions recorded by the \mbox{LHCb}\xspace experiment, corresponding to an integrated luminosity of 9 fb$^{-1}$. The dikaon spectrum in the mass range $m_{KK}<2400\ \text{MeV/}c^2$ is dominated by the $\phi(1020)$ resonance that accounts for almost 70$\%$ of the decay rate. [...]

Identification of charm jets at LHCb / LHCb Collaboration
The identification of charm jets is achieved at LHCb for data collected in 2015-2018 using a method based on the properties of displaced vertices reconstructed and matched with jets. The performance of this method is determined using a dijet calibration dataset recorded by the LHCb detector and selected such that the jets are unbiased in quantities used in the tagging algorithm.

Measurement of the photon polarization in $\Lambda_{b}^{0}$ $\to$ $\Lambda$ $\gamma$ decays / LHCb Collaboration
The photon polarization in $b\to s\gamma$ transitions is measured for the first time in radiative b-baryon decays exploiting the unique spin structure of $\Lambda_{b}^{0}\to\Lambda\gamma$ decays. A data sample corresponding to an integrated luminosity of $6\;\mathrm{fb^{-1}}$ collected by the LHCb experiment in $pp$ collisions at a center-of-mass energy of $13\;\mathrm{TeV}$ is used. [...]

Study of $ {\mathrm{B}}_{\mathrm{c}}^{+} $ decays to charmonia and three light hadrons / LHCb Collaboration
Using proton-proton collision data, corresponding to an integrated luminosity of $9fb^{-1}$ collected with the LHCb detector, seven decay modes of the $B_c^+$ meson into a $J/\psi$ or $\psi(2S)$ meson and three charged hadrons, kaons or pions, are studied. The decays $B_c^+\rightarrow ( \psi(2S) \rightarrow J/\psi \pi^+ \pi^-)\pi^+ $, $B_c^+\rightarrow \psi(2S)\pi^+\pi^+\pi^-$, $B_c^+\rightarrow J/\psi K^+\pi^+\pi^-$ and $B_c^+\rightarrow J/\psi K^+K^+K^-$ are observed for the first time, and evidence for the $B_c^+\rightarrow \psi(2S)K^+K^-\pi^+$ decay is found, where $J/\psi$ and $\psi(2S)$ mesons are reconstructed in their dimuon decay modes.

Angular Analysis of $D^0 \to \pi^+\pi^-\mu^+\mu^-$ and $D^0 \to K^+K^-\mu^+\mu^-$ Decays and Search for $CP$ Violation / LHCb Collaboration
The first full angular analysis and an updated measurement of the decay-rate $CP$ asymmetry of the $D^0 \to \pi^+\pi^-\mu^+\mu^-$ and $D^0 \to K^+K^-\mu^+\mu^-$ decays are reported. The analysis uses proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV. [...]

Centrality determination in heavy-ion collisions with the LHCb detector / LHCb Collaboration
The centrality of heavy-ion collisions is directly related to the medium created therein. A procedure to determine the centrality of collisions with the LHCb detector is implemented for lead-lead collisions at $\sqrt{s_{\scriptscriptstyle\text{NN}}}=5\, \mathrm{TeV}$ and lead-neon fixed-target collisions at $\sqrt{s_{\scriptscriptstyle\text{NN}}}=69\, \mathrm{GeV}$.

Observation of Two New Excited $\Xi_b^0$ States Decaying to $\Lambda^0_b K^- \pi^+$ / LHCb Collaboration
Two narrow resonant states are observed in the ${\it\Lambda}_b^0 K^-\pi^+$ mass spectrum using a data sample of proton-proton collisions at a center-of-mass energy of 13$\rm TeV$, collected by the LHCb experiment and corresponding to an integrated luminosity of $6~{\rm fb}^{-1}$. The minimal quark content of the ${\it\Lambda}_b^0 K^-\pi^+$ system indicates that these are excited ${\it\Xi}_b^0$ baryons. [...]

Simultaneous determination of CKM angle $\gamma$ and charm mixing parameters / LHCb Collaboration
A combination of measurements sensitive to the $C\!P$ violation angle $\gamma$ of the Cabibbo--Kobayashi--Maskawa 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 combined for the first time. [...]
