Observation of $B_c^+ \to D h^+ h^-$ decays / LHCb Collaboration
Searches are presented for $B_{c}^{+} \to D h^+ h^-$ decays, where $D$ is a charmed meson and $h^{\pm}$ is a charged pion or kaon, using $pp$ collision data collected by the LHCb experiment corresponding to an integrated luminosity of $9~\text{fb}^{-1}$. [...]

First evidence of CP violation in beauty baryon to charmonium decays / LHCb Collaboration
A study of the difference in the $CP$ asymmetries between ${\Lambda}^0_b \rightarrow J / \psi p \pi^-$ and ${\Lambda}^0_b \rightarrow J / \psi p K^-$ decays, $\Delta {\cal A}_{CP}$, is performed using proton-proton collision data collected by the LHCb experiment in the years 2015-2018, corresponding to an integrated luminosity of $6\,{\rm fb}^{-1}$. [...]

A model-independent measurement of the CKM angle $\gamma$ in the decays $B^\pm\to[K^+K^-\pi^+\pi^-]_D h^\pm$ and $B^\pm\to[\pi^+\pi^-\pi^+\pi^-]_D h^\pm$ ($h = K, \pi$) / LHCb Collaboration
A model-independent determination of the CKM angle $\gamma$ is presented, using the $B^\pm\to[K^+K^-\pi^+\pi^-]_D h^\pm$ and $B^\pm\to[\pi^+\pi^-\pi^+\pi^-]_D h^\pm$ decays, with $h=K,\pi$ [...]

Unveiling the shape of the $^{20}$Ne nucleus by measuring the flow coefficients with cumulants in PbNe and PbAr collisions at $\sqrt{s_{NN}} = 70.9$ GeV / LHCb Collaboration
The anisotropic flow coefficients $v_n$ quantify the collective medium response to the initial spatial anisotropy of the overlapping region in ion collisions and serve as sensitive probes of both the medium properties and shape of nuclear initial states. [...]
