Forward rapidity $ψ(\mathrm{2S})$ meson production in pp, p-Pb and Pb-Pb collisions with ALICE at the LHC

The ALICE Collaboration has studied the inclusive $ψ(\mathrm{2S})$ meson production in pp, p-Pb and Pb-Pb collisions at the CERN LHC. The $ψ(\mathrm{2S})$ is detected through its decay to a muon pair, using the forward Muon Spectrometer, which covers the pseudo-rapidity range $-4<η<-2.5$. The $ψ(\mathrm{2S})$ production cross sections in pp collisions are presented as a function of rapidity (y) and transverse momentum ($p_{\mathrm{T}}$). In p-Pb collisions, $ψ(\mathrm{2S})$ results are compared to the J/$ψ$ ones by the ratio of their production cross sections as a function of rapidity, transverse momentum and event activity. The $ψ(\mathrm{2S})$ nuclear modification factor, $R_{\mathrm{pA}}$, is also discussed. The results show a $ψ(\mathrm{2S})$ suppression compared to the one observed for the J/$ψ$ meson and are not described by theoretical models including cold nuclear matter effects as nuclear shadowing and energy loss. Finally, the preliminary results of $ψ(\mathrm{2S})$ meson production in Pb-Pb collisions are shown in two $p_{\mathrm{T}}$ ranges as a function of the collision centrality.

J/$ψ$ and $ψ$(2S) production in p-Pb collisions at $\sqrt{s_{NN}}=\mathrm{5.02}$ TeV with ALICE at the LHC

The ALICE Collaboration has studied the inclusive J/$ψ$ and $ψ(\mathrm{2S})$ production in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV, at the CERN LHC. The J/$ψ$ measurement is performed in the $μ^{+}μ^{-}$ and in the $e^{+}e^{-}$ decay channels, down to zero $p_{\mathrm{T}}$. The results are in fair agreement with theoretical predictions. The $ψ(\mathrm{2S})$ measurement has also been performed. In particular, a smaller $ψ(\mathrm{2S})$ nuclear modification factor, with respect to the J$/ψ$ one, has been observed.

J/$ψ$ and $ψ$(2S) production in p-Pb collisions with ALICE at the LHC

The ALICE collaboration has studied the inclusive J/$ψ$ and $ψ(\mathrm{2S})$ production in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV at the CERN LHC. The J/$ψ$ measurement is performed in the $μ^{+}μ^{-}$ ( - 4.46 < $y_{cms}$ < - 2.96 and 2.03 < $y_{cms}$ < 3.53 ) and in the $e^{+}e^{-}$ ( - 1.37 < $y_{cms}$ < 0.46 ) decay channels, down to zero transverse momentum. The results are in fair agreement with theoretical predictions based on nuclear shadowing, as well as with models including, in addition, a contribution from partonic energy loss. Finally, the $ψ(\mathrm{2S})$ measurement in the $μ^{+}μ^{-}$ decay channel has been performed. In particular, a significantly smaller $ψ(\mathrm{2S})$ nuclear modification factor, with respect to the J$/ψ$ one, has been observed.
