Description

This work is devoted to charmonia prompt and b-decays production study via charmonia decays to $\varphi \varphi$ and $p\bar{p}$ in order to test existing Non-Relativistic QCD predictions. Using decays to $\varphi$-meson pairs, the inclusive production of ${\chi }_{c0,1,2}$ in b-hadron decays is studied with pp collision data corresponding to an integrated luminosity of $\int \mathcal{L}dt=3.0f{b}^{-1}$, collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. Differential ${\eta }_c(1S)$ production using its decay to $p\bar{p}$ in proton-proton collisions at the center of mass energy $\sqrt{s}=13TeV$ with an integrated luminosity of $\int \mathcal{L}dt=2.0f{b}^{-1}$ was measured.
