   Inclusive J/$\psi$ and $\psi$(2S) production in pp collisions at $\sqrt{s}=7$ TeV at forward rapidity with ALICE at LHC

   Biswarup Paul (for the ALICE Collaboration)🇮🇳

   The ALICE collaboration has studied inclusive J/$\psi$ and $\psi$(2S) production at forward rapidities in pp collisions at $\sqrt{s}=7$ TeV with the ALICE Muon Spectrometer. The analysis has been carried out on a data sample corresponding to an integrated luminosity ${\mathcal{L}}_{\mathrm{int}}$ = 1.35 pb${}^{-1}$. The production cross-sections of J/$\psi$ and $\psi$(2S), integrated over \pt\ (0 $<$ \pt\ $<$ 20 GeV/$c$) and \y\ (2.5 $<$ \y\ $<$ 4), have been measured. The J/$\psi$ and $\psi$(2S) differential cross-sections, in transverse momentum and rapidity, have also been measured. The results have been compared with the previous ALICE published results at ${\mathcal{L}}_{\mathrm{int}}$ = 15.6 nb${}^{-1}$ and also with the measurement performed by LHCb collaboration. The $\psi$(2S)/J/$\psi$ production ratio (acceptance corrected) integrated over \pt\ and \y\ has been measured. This ratio have also been measured as a function of transverse momentum and rapidity. The ratio as a function of transverse momentum has been compared with the LHCb measurement.
