Search for $CP$ violation in $\Xi_c^+\rightarrow pK^-\pi^+$ decays using model-independent techniques / LHCb Collaboration
A first search for $CP$ violation in the Cabibbo-suppressed $\Xi_c^+\rightarrow pK^-\pi^+$ decay is performed using both a binned and an unbinned model-independent technique in the Dalitz plot. The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of $3.0~\rm fb^{-1}$, and collected by the LHCb experiment at centre-of-mass energies of $7$ and $8~\rm TeV$.

Precision measurement of the $B_{c}^{+}$ meson mass / LHCb Collaboration
A precision measurement of the $B_{c}^{+}$ meson mass is performed using proton-proton collision data collected with the LHCb experiment at centre-of-mass energies of $7, 8$ and $13$ TeV, corresponding to a total integrated luminosity of $9.0$ fb$^{-1}$. The $B_{c}^{+}$ mesons are reconstructed via the decays $B_{c}^{+} \rightarrow J\mskip -3mu/\mskip -2mu\psi\mskip 2mu \pi^+$, $B_{c}^{+} \rightarrow J\mskip -3mu/\mskip -2mu\psi\mskip 2mu \pi^+ \pi^- \pi^+$, $B_{c}^{+} \rightarrow J\mskip -3mu/\mskip -2mu\psi\mskip 2mu p \bar{p} \pi^+$, $B_{c}^{+} \rightarrow J\mskip -3mu/\mskip -2mu\psi\mskip 2mu D_{s}^{+}$, $B_{c}^{+} \rightarrow J\mskip -3mu/\mskip -2mu\psi\mskip 2mu D^{0} K^{+}$ and $B_{c}^{+} \rightarrow B_{s}^{0} \pi^+$.

Observation of new $\Xi_c^0$ baryons decaying to $\Lambda_c^+K^-$ / LHCb Collaboration
The $\Lambda_c^+K^-$ mass spectrum is studied with a data sample of $pp$ collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb$^{-1}$ collected by the LHCb experiment. Three $\Xi_c^0$ states are observed with a large significance and their masses and natural widths are measured to be \begin{eqnarray*} m(\Xi_c(2923)^0)&=& 2923.04 \pm 0.25 \pm 0.20 \pm 0.14 ~\mathrm{MeV},\\ \Gamma(\Xi_c(2923)^0) &=& 7.1 \pm 0.8 \pm 1.8~\mathrm{MeV}, \end{eqnarray*} \begin{eqnarray*} m(\Xi_c(2939)^0) &=& 2938.55 \pm 0.21 \pm 0.17 \pm 0.14~\mathrm{MeV},\\ \Gamma(\Xi_c(2939)^0) &=& 10.2 \pm 0.8 \pm 1.1~\mathrm{MeV}, \end{eqnarray*} \begin{eqnarray*} m(\Xi_c(2965)^0) &=& 2964.88 \pm 0.26 \pm 0.14 \pm 0.14~\mathrm{MeV}, \\ \Gamma(\Xi_c(2965)^0) &=& 14.1 \pm 0.9 \pm 1.3~\mathrm{MeV}, \end{eqnarray*} where the uncertainties are statistical, systematic, and due to the limited knowledge of the $\Lambda_c^+$ mass.

Measurement of the shape of the $ {B}_s^0\to {D}_s^{\ast -}{\mu}^{+}{\nu}_{\mu } $ differential decay rate / LHCb Collaboration
The shape of the $B_s^0\rightarrow D_s^{*-}\mu^+\nu_{\mu}$ differential decay rate is obtained as a function of the hadron recoil using proton-proton collision data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.7 fb$^{-1}$ collected by the LHCb detector.

Measurement of the branching fraction of the decay $B_s^0\to K_S^0 K_S^0$ / LHCb Collaboration
A measurement of the branching fraction of the decay $B_s^0 \to K_S^0 K_S^0$ is performed using proton-proton collision data corresponding to an integrated luminosity of 5 fb$^{-1}$ collected by the LHCb experiment between 2011 and 2016. The branching fraction is determined to be$$ \mathcal{B}(B_s^0 \to K_S^0 K_S^0) = [8.3 \pm 1.6 (\rm{stat}) \pm 0.9 (\rm{syst}) \pm 0.8 (\rm{norm}) \pm 0.3 (f_s/f_d)] \times 10^{-6}, $$ where the first uncertainty is statistical, the second is systematic, and the third and fourth are due to uncertainties on the $B^0 \to \phi K_S^0$ branching fraction and the ratio of hadronization fractions $f_s/f_d$ [...]
