A bstractThe effects of parton energy loss in cold nuclear matter on heavy-quarkonium suppression in p-A collisions are studied. It is shown from first principles that at large quarkonium energy E and small production angle in the nucleus rest frame, the medium-induced energy loss scales as E. Using this result, a phenomenological model depending on a single free parameter is able to reproduce J/ψ and Υ suppression data in a broad xF -range and at various center-of-mass energies. These results… 

Quarkonium suppression in heavy-ion collisions from coherent energy loss in cold nuclear matter

A bstractThe effect of parton energy loss in cold nuclear matter on the suppression of quarkonia (J/ψ, ϒ) in heavy-ion collisions is investigated, by extrapolating a model based on coherent radiative

J/\psi suppression in p-A collisions from charm quark energy loss in cold nuclear matter

The energy loss effect of charm quarks in cold nuclear matter on suppression in p-A collisions is studied. By means of two parametrizations of quark energy loss, the leading-order computations for

Quarkonium Suppression from Coherent Energy Loss in Fixed-Target Experiments Using LHC Beams

Quarkonium production in proton-nucleus collisions is a powerful tool to disentangle cold nuclear matter effects. A model based on coherent energy loss is able to explain the available quarkonium

Open Heavy Flavor in QCD Matter and in Nuclear Collisions

We review the experimental and theoretical status of open heavy-flavor (HF) production in high-energy nuclear collisions at RHIC and LHC. We first overview the theoretical concepts and pertinent

Measurement of the J/ψ production in p-Pb collisions at the LHC with the ALICE muon spectrometer

Hard probes represent one of the hottest topics of the modern high energy physics. The production mechanism of quarkonia (mesons composed of a charm or beauty quark and its antiquark) in hadronic

Overview of quarkonium production in heavy-ion collisions at LHC

Quarkonium has been regarded as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma (QGP) in heavy-ion collisions. Recent data

Latest Results on Quarkonium Production from CMS

. The understanding of quarkonium production in heavy-ion collisions requires the inclusion of many phenomena such as dissociation in the QGP, partonic energy loss, statistical recombination, on top

Study of ϒ Production and Cold Nuclear Matter Effects in pPb Collisions at √s[subscript NN] = 5 TeV

The production of J/ψ mesons with rapidity 1.5 < y < 4.0 or −5.0 < y < −2.5 and transverse momentum pT < 14 GeV/c is studied with the LHCb detector in proton-lead collisions at a nucleon-nucleon



J/ψ suppression in p-A collisions from parton energy loss in cold QCD matter.

The results strongly support energy loss as a dominant effect in quarkonium suppression and give some hint on its hadroproduction mechanism suggesting color neutralization to happen on long time scales.

Energy dependence of J/ψ absorption in proton-nucleus collisions

Charmonium states are expected to be considerably suppressed in the case of quark-gluon plasma formation in high-energy heavy-ion collisions. However, a robust identification of suppression patterns

Cold-nuclear-matter effects on heavy-quark production in d+Au collisions at sqrt[S(NN)]=200 GeV.

The PHENIX experiment has measured electrons and positrons at midrapidity from the decays of hadrons containing charm and bottom quarks produced in d+Au and p+p collisions, and shows that the mass-dependent Cronin enhancement observed at the Relativistic Heavy Ion Collider extends to the heavy D meson family.

J/ψ suppression at forward rapidity in Pb-Pb collisions at √s(NN) = 2.76 TeV.

Models including J/ψ production from charm quarks in a deconfined partonic phase can describe the data, and features appear significantly different from measurements at lower collision energies.

Radiative energy loss of high-energy quarks in finite-size nuclear matter and quark-gluon plasma

The induced gluon radiation of a high-energy quark in a finite-size QCD medium is studied. For a sufficiently energetic quark produced inside a medium we find the radiative energy loss ΔEq∝L2, where
