“…The comparison of NA3 [7], E772/ E866 [8,10], as well as PHENIX [15] measurements made it possible to rule out a scaling of J=c suppression in the target parton momentum fraction x 2 , indicating a violation of factorization in charm hadroproduction [16]. This observation consequently ruled out the nuclear modifications of parton densities in the target as being a dominant effect.…”

Revisiting scaling properties of medium-induced gluon radiation

2011

Discussing the general case of a hard partonic production process, we show that the notion of parton energy loss is not always sufficient to fully address medium-induced gluon radiation. The broader notion of gluon radiation associated to a hard process has to be used, in particular when initial and final state radiation amplitudes interfere, making the medium-induced radiated energy different from the energy loss of any well-identified parton. Our arguments are first presented in an abelian QED model, and then applied to large-xF quarkonium hadroproduction. In this case, we show that the medium-induced radiated energy is qualitatively similar (but not identical) to the radiative energy loss of an "asymptotic massive parton" undergoing transverse momentum broadening when travelling through the nucleus. In particular, it scales as the incoming parton energy, which suggests to reconsider gluon radiation as a possible explanation of large-xF quarkonium suppression in p-A collisions. We expect a similar effect in open heavy-flavour and possibly light-hadron hadroproduction at large xF, depending on the precise definition of the nuclear suppression factor in the latter case.Comment: 16 pages, 11 figures.

“…In heavy-ion collision experiments, the QGP created is expected to cause a suppression of J=c creation due to the dissociation of charmonia in the deconfinement phase of QCD [1]. Suppression of J=c particles was actually observed in several experiments at the Super Proton Synchrotron [2] and the Relativistic Heavy Ion Collider [3]. Here, not only J=c but also c and c 0 states contribute to the total yield of J=c [4].…”

Charmonium spectral functions with the variational method in zero and finite temperature lattice QCD

et al. 2011

View full text Add to dashboard Cite

We propose a method to evaluate spectral functions on the lattice based on a variational method. On a lattice with a finite spatial extent, spectral functions consist of discrete spectra only. Adopting a variational method, we calculate the locations and the heights of spectral functions at low-lying discrete spectra. We first test the method in the case of analytically solvable free Wilson quarks at zero and finite temperatures and confirm that the method well reproduces the analytic results for low-lying spectra. We find that we can systematically improve the results by increasing the number of trial states. We then apply the method to calculate the charmonium spectral functions for S and P-wave states at zero-temperature in quenched QCD and compare the results with those obtained using the conventional maximum entropy method (MEM). The results for the ground state are consistent with the location and the area of the first peak in spectral functions from the MEM, while the variational method leads to a mass which is closer to the experimental value for the first excited state. We also investigate the temperature dependence of the spectral functions for S-wave states below and above T c . We obtain no clear evidences for dissociation of J=c and c up to 1:4T c .

“…In proton (deuteron)-nucleus collisions, p(d)+A, the formation of a large region of deconfined and hot QGP matter was not expected to occur. Therefore, the observed suppression of quarkonium yields in these systems with respect to pp collisions [4][5][6][7] has traditionally been attributed to CNM effects.…”

The modification of the production of J/ψ, ψ(2S), and Υ (nS) (n = 1, 2, 3) in p+Pb collisions with respect to their production in pp collisions has been studied. The p+Pb and pp datasets used in this paper correspond to integrated luminosities of 28 nb −1 and 25 pb −1 respectively, collected in 2013 and 2015 by the ATLAS detector at the LHC, both at a centre-of-mass energy per nucleon pair of 5.02 TeV. The quarkonium states are reconstructed in the dimuon decay channel. The yields of J/ψ and ψ(2S) are separated into prompt and non-prompt sources. The measured quarkonium differential cross sections are presented as a function of rapidity and transverse momentum, as is the nuclear modification factor, R pPb for J/ψ and Υ (nS). No significant modification of the J/ψ production is observed while Υ (nS) production is found to be suppressed at low transverse momentum in p+Pb collisions relative to pp collisions. The production of excited charmonium and bottomonium states is found to be suppressed relative to that of the ground states in central p+Pb collisions.
