The suppression of heavy quarkonium states such as J/psi, psi(2S) and Upsilon(nS) in heavy-ion collisions, with respect to proton-proton collisions, plays an important role in studying the hot and dense medium formed in the larger collision systems. A full assessment of this suppression requires understanding of nuclear effects which may affect the production of quarkonium states even in the...

The ALICE Collaboration has studied the inclusive $\mathrm{J}/\psi$ and $\psi(\mathrm{2S})$ production in p-Pb collisions at the nucleon-nucleon centre of mass energy $\sqrt{s_{NN}}=5.02$ TeV at the CERN LHC. The strongly bound $\mathrm{J}/\psi$ and the loosely bound $\psi(\mathrm{2S})$ are detected through their decays to muon pairs in two configurations with inverted beam directions, with...

Proton-lead and lead-proton data taking during 2013 has allowed LHCb
to expand its core physics program into the regime of heavy ion
physics. Results include the first forward measurement of Z production
in proton-lead collisions as well as a measurement of the nuclear
modification factor and forward-backward production of prompt and
displaced J/psi, psi(2S) and Upsilons. Angular particle...

We make a systematic study of the modifications of $J/\psi$ and $\Upsilon(1S)$
production
in $p+$Pb collisions at $\sqrt{s_{_{NN}}} = 5$ TeV at the LHC. We compare
the uncertainties in the EPS09 shadowing parameterization to the calculated
mass and scale uncertainties obtained employng the EPS09 NLO central set.
We study the dependence of the results on the proton parton density and...

Inclusive production of $J/\psi$ mesons, especially at forward rapidities, is an important probe of small-x gluons in protons and nuclei. In this work we re-evaluate the production cross sections in the Color Glass Condensate framework, where the process is described by a large x gluon from the probe splitting into a quark pair and eikonally interacting with the target proton or nucleus. Using...
