An amplitude analysis of the $B^-\to\Lambda_c^+\overline{p}\pi^-$ decay is performed using proton-proton collision data, corresponding to an integrated luminosity of $9\ \text{fb}^{-1}$, collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. In the $\Lambda_c^+\pi^-$ invariant-mass spectrum, the known …

A search for the radiative leptonic decays $B^+\to\mu^+\nu_\mu\gamma$ and $B^+_c\to\mu^+\nu_\mu\gamma$ is performed using proton-proton collision data collected with the LHCb experiment at a center-of-mass energy of $13~{\rm TeV}$, corresponding to an integrated luminosity of~$5.4~{\rm fb}^{-1}$. No evidence for an excess of events …

A measurement of the CKM angle $\gamma$ using the decay channels $B^{\pm}\rightarrow DK^{\pm}$ and $B^{\pm}\rightarrow D\pi^{\pm}$, where the $D$ meson decays to $D\rightarrow K_{\rm S}^{0}\pi^{+}\pi^{-}$ or $D\rightarrow K_{\rm S}^{0}K^{+}K^{-}$, is performed with a data sample corresponding to an integrated luminosity of 5.8 …

This paper presents the first measurement of the forward-backward asymmetry, $A_{\rm FB}$, and the flat term, $F_{H}$, that parameterise the angular distribution of the $B^+\to\pi^+\mu^+\mu^-$ decay. The proton-proton collision dataset used in the analysis corresponds to an integrated luminosity of 9 fb$^{-1}$, …
