ALICE is the heavy-ion experiment at CERN Large Hadron Collider. The continuously took data during first physics campaign of machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe running environment handling procedures, discuss performance detectors analysis methods for various observables.
This writeup is a compilation of the predictions for forthcoming Heavy Ion Program at Large Hadron Collider, as presented CERN Theory Institute 'Heavy Collisions LHC - Last Call Predictions', held from May 14th to June 10th 2007.
The Large Hadron electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) energy and intensity frontier particle physics. Exploiting recovery technology, it collides a novel, intense beam with proton or ion from High Luminosity--Large (HL-LHC). accelerator interaction region are for concurrent electron-proton proton-proton operation. This report represents an update Conceptual Design Report (CDR) LHeC, published in 2012. It comprises new results on parton...
Recent results from proton(deuteron)–nucleus collisions at RHIC and LHC energies have shown an unexpected suppression of excited quarkonium states as compared to their ground states. In particular, stronger the ψ(2S) relative J/ψ has been detected. Similar observations were made lower easily explained by nuclear absorption. At higher energies, a similar explanation would violate Heisenberg principle, since calculations based on uncertainty principle lead charmonium formation time expected be...
The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals identified: characterisation of macroscopic long wavelength Quark-Gluon Plasma (QGP) properties unprecedented precision, investigation microscopic parton dynamics underlying QGP properties, development a unified picture particle production from small (pp) to large (nucleus--nucleus) systems, exploration densities in nuclei broad ($x$, $Q^2$) kinematic range...
Open and hidden heavy-flavor physics in high-energy nuclear collisions are entering a new exciting stage towards reaching clearer understanding of the experimental results with possibility to link them directly advancement lattice Quantum Chromo-Dynamics (QCD). Recent from experiments theoretical developments regarding open dynamics have been debated at Lorentz Workshop Tomography Quark-Gluon Plasma Heavy Quarks, which was held October 2016 Leiden, The Netherlands. In this contribution, we...
Abstract The structure of exotic resonances that do not trivially fit the usual quark model expectations has been a matter intense scientific debate during last two decades. A possible way estimating size these states is to study their behavior when immersed in QCD matter.

This document summarizes the efforts of EMMI Rapid Reaction Task Force on "Suppression and (re)generation quarkonium in heavy-ion collisions at LHC", centered around their 2019 2022 meetings. It provides a review existing experimental results theoretical approaches, including lattice QCD calculations semiclassical quantum approaches for dynamical evolution quarkonia quark-gluon plasma as probed high-energy collisions. The key ingredients transport models are itemized to facilitate...
It is shown that the critical threshold for percolation of overlapping strings exchanged in heavy ion collisions can naturally explain sharp strong suppression $J/\ensuremath{\psi}$ by experimental data on central Pb-Pb collisions, which does not occur O-U and S-U collisions.
We present our results on charmonium production at the Large Hadron Collider energies within comover interaction model. The formalism includes both dissociation of $J/ψ$'s and possible secondary $J/ψ$ through recombination. estimation this effect is made without involving free parameters. model also incorporates an analytic treatment initial-state nuclear shadowing. With these tools, successfully describes centrality, transverse momentum rapidity dependence experimental data from PbPb...
We discuss the dependence of J/\psi\ production on charged particle multiplicity in proton-proton collisions at LHC energies. show that, framework parton saturation or string interaction models, hard exhibits a significant growth with multiplicity, which is stronger than linear high density domain. This departure from linearity, that should affect any observable, applies for central rapidity region and consequence strong among colour ropes take place Our assumption, existence coherence...
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...
We show that, contrary to recent claims, the $J/\psi$ suppression resulting from its interaction with comovers does not saturate at large transverse energy $E_T$. On contrary, it shows a characteristic structure - change of curvature near knee $E_T$ distribution which is due (or multiplicity) fluctuation, and agrees experimental results.
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 study the potential of X(3872) at finite temperature in Born- Oppenheimer approximation under assumption that it is a tetraquark. argue that, large number colors, good to assume consists real part plus constant imaginary term. The then computed adapting an approach by Rothkopf and Lafferty using as input lattice QCD determinations for hybrids. This model allows us qualitatively estimate which range formation heavy tetraquark possible, propose qualitative picture dissociation state medium....
