Quarkonium production in $p$-Pb collisions with ALICE

ALICE has measured quarkonium production in p-Pb collisions at backward $−4.46 < y_{cms} < −2.96$, mid $−1.37 < y_{cms} < 0.43$ and forward $2.03 < y_{cms} < 3.53$ rapidity $y$ regions down to zero transverse momentum $p_T$. The inclusive $J/\psi$ production has been studied at mid...

Sumario:ALICE has measured quarkonium production in p-Pb collisions at backward $−4.46 < y_{cms} < −2.96$, mid $−1.37 < y_{cms} < 0.43$ and forward $2.03 < y_{cms} < 3.53$ rapidity $y$ regions down to zero transverse momentum $p_T$. The inclusive $J/\psi$ production has been studied at mid-$y$ in p-Pb interactions at $\sqrt{^sNN}=5.02TeV$ and at forward and backward $y$ in p-Pb collisions at $\sqrt{^sNN}=5.02 TeV$ and $8.16 TeV$. The comparison of the $J/\psi$ production to the one of the loosely bound $\psi$ (2S) state is discussed, together with new results on the nuclear modification factors of the $\gamma$(1S) and $\gamma$(2S) states measured at forward and backward $y$. All the results will be compared to those obtained at lower energies and with available theoretical calculations.
