Measurement of the $\ B^0 \to \rho(770)^0 \gamma \ $ branching fraction / LHCb Collaboration
The ratio between the branching fractions of the $B^0\to\rho(770)^0\gamma$ and $B^0\to K^{*}(892)^0\gamma$ decays is measured with proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb${}^{-1}$.

Search for resonances decaying to photon pairs with masses between 4.9 and 19.4 GeV / LHCb Collaboration
A search is presented for axion-like particles (ALPs) with masses between 4.9 and 19.4 GeV decaying to a pair of photons, using proton-proton collisions collected with the LHCb detector during 2018 at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 2.1 fb$^{-1}$.

Precision measurement of the ${\it{\Xi}}_b^0$ baryon lifetime / LHCb Collaboration
A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb$^{-1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of the lifetime of the ${\it{\Xi}}_b^0$ baryon to that of the ${\it{\Lambda}}_b^0$ baryon, $r_{\tau}\equiv\tau_{{\it{\Xi}}_b^0}/\tau_{{\it{\Lambda}}_b^0}$. The value ${r_{\tau}^{\rm Run\,2}=1.004\pm0.009\pm0.006}$ is obtained, where the first uncertainty is statistical and the second systematic. [...]

First observation of the $\mathit{\Lambda}_b^{0}\!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}K^{+}K^{-}$ decay and search for pentaquarks in the $\mathit{\Lambda}_{c}^{+}D_{s}^{-}$ system / LHCb Collaboration
The $\mathit{\Lambda}_b^{0}\!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}K^{+}K^{-}$ decay is observed for the first time using the data sample from proton-proton collisions recorded at a center-of-mass energy of $13\,\text{TeV}$ with the LHCb detector, corresponding to an integrated luminosity of $6\,\text{fb}^{-1}$. The ratio of branching fraction to that of $\mathit{\Lambda}_b^{0} \!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}$ decays is measured as $0.0141 \pm 0.0019 \pm 0.0012$, where the first uncertainty is statistical and the second systematic.

More visualisation of decay-time-dependent asymmetries in multibody B-meson decays / Gershon, Tim (Warwick U.) ; Latham, Thomas (Warwick U.) ; Li, Peilian (CERN ; Beijing, Inst. High Energy Phys.) ; Morris, Andy (Marseille, CPPM) ; Qian, Wenbin (Beijing, Inst. High Energy Phys.) ; Whitehead, Mark (Glasgow U.) ; Xu, Ao (INFN, Pisa ; Pisa, Scuola Normale Superiore)
Methods have been proposed recently to weight data in order to allow visualisation of CP-violation effects in transitions of neutral B mesons to multibody final states that are not CP-eigenstates. These are useful since integration of the unweighted data over the phase space would otherwise wash out the effects of interest. [...]

Updated measurement of $CP$ violation and polarisation in $B^0_s \rightarrow J/\psi \overline{K}{}^{*}\kern-1pt(892)^{0}$ decays / LHCb Collaboration
A time-integrated angular analysis of the decay $B^0_s \rightarrow J/\psi \overline{K}{}^{*}\kern-1pt(892)^{0}$, with $J/\psi \rightarrow \mu^{+} \mu^{-}$ and $\overline{K}{}^{*}\kern-1pt(892)^{0} \rightarrow K^{-} \pi^{+}$, is presented. The analysis employs a sample of proton-proton collision data collected by the LHCb experiment during 2015-2018 at a centre-of-mass energy of $13 \text{TeV}$, corresponding to an integrated luminosity of $6 \text{fb}^{-1}$.
