Evidence for $B^-\rightarrow D^{**0}\tau^-\overline{\nu}_{\tau}$ decays / LHCb Collaboration
The first evidence for the decay $B^-\rightarrow D^{**0}\tau^-\overline{\nu}_{\tau}$ is obtained using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb$^{-1}$ , at centre-of-mass energies of 7, 8 and 13 Tev. [...]

Modification of heavy quark hadronization in high-multiplicity collisions at LHCb / Gu, Chenxi (LLR, Palaiseau) /LHCb Collaboration
The baryon-to-meson and meson-to-meson production ratios of heavy quarks are well suited to study the hadronization mechanism. Here we will present LHCb results on the production ratios of $B_{s}^{0}/B^{0}$, $D_{s}^{+}/D^{+}$ and $\Lambda_{c}^{+}/D^{0}$ in differents collision systems. [...]

Measurement of the multiplicity dependence of Upsilon production ratios in pp collisions at centre of mass energy 13 TeV / LHCb Collaboration
The $\mit{\Upsilon}(\mathrm{2}S)$ and $\mit{\Upsilon}(\mathrm{3}S)$ production cross-sections are measured relative to that of the $\mit{\Upsilon}(\mathrm{1}S)$ meson, as a function of charged-particle multiplicity in proton-proton collisions at a centre-of-mass energy of $13$ TeV. [...]
