We update our previous studies of nuclear-matter effects on J/Psi production in proton-nucleus for the recent LHC pPb runs at sqrt(s_NN)=5 TeV. have analysed modification gluon PDFs nucleus, using an exact kinematics a 2->2 process, namely g+g->J/Psi+g as expected from LO pQCD. This allows to constrain transverse-momentum while computing nuclear factor different rapidities, unlike with usual simplified kinematics. Owing absence measurement pp collisions same sqrt(s_NN) and owing significant...
Cold nuclear matter effects on J/psi production in proton-nucleus and nucleus-nucleus collisions are evaluated taking into account the specific kinematics at partonic level, shadowing of initial parton distributions absorption matter. We consider two different processes for c-cbar pair production: one with collinear gluons a recoiling gluon final state other carrying intrinsic transverse momentum. Our results compared to RHIC observables. The smaller values modification factor R_AA forward...
We report on the opportunities for spin physics and Transverse-Momentum Dependent distribution (TMD) studies at a future multi-purpose fixed-target experiment using proton or lead ion LHC beams extracted by bent crystal. The multi-TeV allow most energetic experiments ever performed, opening new domains of particle nuclear complementing that collider physics, in particular RHIC EIC projects. luminosity achievable with AFTER@LHC typical targets would surpass more 3 orders magnitude similar...
Predictions made in Albacete et al. [Int. J. Mod. Phys. E 22 (2013) 1330007] prior to the LHC [Formula: see text]Pb run at text] TeV are compared currently available data. Some predictions shown here have been updated by including same experimental cuts as additional also presented, especially for quarkonia, that were provided experiments before data public but too late original publication.
We have carried out a wide study of cold nuclear matter (CNM) effects on $J/\ensuremath{\psi}$ production in $d$Au, CuCu and AuAu collisions at $\sqrt{{s}_{\mathit{NN}}}=200$ GeV. studied the three different gluon-shadowing parametrizations, using usual simplified kinematics for which momentum gluon recoiling against is neglected as well an exact $2\ensuremath{\rightarrow}2$ process; namely $g+g\ensuremath{\rightarrow}J/\ensuremath{\psi}+g$ expected from LO pQCD. shown that rapidity...
We outline the opportunities to study with high precision interface between nuclear and particle physics, which are offered by a next generation multi-purpose fixed-target experiment exploiting proton ion LHC beams extracted bent crystal.
We report on the studies of Transverse-Momentum-Dependent distributions (TMDs) at a future fixed-target experiment –AFTER@LHC– using [Formula: see text] or Pb ion LHC beams, which would be most energetic ever performed. AFTER@LHC opens new domains particle and nuclear physics by complementing collider-mode experiments, in particular those RHIC EIC projects. Both with an extracted beam bent crystal internal gas target, luminosity achieved surpasses that up to 3 orders magnitude. With...

We investigate the cold nuclear matter effects on J/ψ production, whose understanding is fundamental to studying quark–gluon plasma. Two of these are particular relevance: shadowing parton distributions and absorption pair. If J/ψ's not produced via a 2 → 1 process as suggested by recent theoretical works, one has modify accordingly way computing shadowing. This naturally induces differences in cross-section fit data. A careful analysis differences, however, requires taking into account...
We study the impact of different cold nuclear matter effects both on J/ψ and ψ' production, among them modification gluon distribution in bound nucleons, commonly known as shadowing, survival probability for a state to escape nucleus -the absorption. Less conventional such saturation fractional energy loss are also discussed. pay particular attention recent PHENIX preliminary data production dAu collisions at = 200 GeV, which show strong suppression central collisions, 5 times larger than...

We argue that the concept of a multi-purpose fixed-target experiment with proton or lead-ion LHC beams extracted by bent crystal would offer number ground-breaking precision-physics opportunities. The multi-TeV will allow for most energetic experiments ever performed. mode has advantage allowing high luminosities, spin measurements polarised target, and access over full backward rapidity domain --uncharted until now-- up to x_F ~ -1.
