“…In the pure melting scenario, the relative production of ψ(2S) with respect to J/ψ is expected to be very small at the LHC [4], which is not the case if recombination occurs [16,17]. J/ψ suppression was observed experimentally in the most central heavy-nucleus collisions at the SPS [18,19], RHIC [20][21][22][23] and LHC [24][25][26][27][28], ranging from a center-of-mass energy per nucleon pair ( √ s NN ) of about 17 GeV to 2.76 TeV. The ψ(2S) suppression was measured at the SPS [29] and the LHC [30].…”

The production of J/ψ and ψ(2S) was studied with the ALICE detector in Pb-Pb collisions at the LHC. The measurement was performed at forward rapidity (2.5 < y < 4) down to zero transverse momentum (p t ) in the dimuon decay channel. Inclusive J/ψ yields were extracted in different centrality classes and the centrality dependence of the average p t is presented. The J/ψ suppression, quantified with the nuclear modification factor (R AA ), was measured as a function of centrality, transverse momentum and rapidity. Comparisons with similar measurements at lower collision energy and theoretical models indicate that the J/ψ production is the result of an interplay between color screening and recombination mechanisms in a deconfined partonic medium, or at its hadronization. Results on the ψ(2S) suppression are provided via the ratio of ψ(2S) over J/ψ measured in pp and Pb-Pb collisions.

We present a lattice study of the equation of state in Yang-Mills theory based on the exceptional G 2 gauge group. As is well-known, at zero temperature this theory shares many qualitative features with real-world QCD, including the absence of colored states in the spectrum and dynamical string breaking at large distances. In agreement with previous works, we show that at finite temperature this theory features a first-order deconfining phase transition, whose nature can be studied by a semi-classical computation. We also show that the equilibrium thermodynamic observables in the deconfined phase bear striking quantitative similarities with those found in SU(N ) gauge theories: in particular, these quantities exhibit nearly perfect proportionality to the number of gluon degrees of freedom, and the trace anomaly reveals a characteristic quadratic dependence on the temperature, also observed in SU(N ) Yang-Mills theories (both in four and in three spacetime dimensions). We compare our lattice data with analytical predictions from effective models, and discuss their implications for the deconfinement mechanism and high-temperature properties of strongly interacting, non-supersymmetric gauge theories. Our results give strong evidence for the conjecture that the thermal deconfining transition is governed by a universal mechanism, common to all simple gauge groups.

“…Hidden heavy-flavor (J /ψ) production has also been extensively measured in heavy-ion collisions [16,17]. The production of J /ψ mesons is expected to be affected by the formation of a quark-gluon plasma due to the interplay of several competing mechanisms, including suppression due to a color screening mechanism similar to the Debye screening in QED [18] and enhancement due to the coalescence of uncorrelated cc pairs from the hot medium [19][20][21].…”

Background: Heavy-flavor production in p + p collisions is a good test of perturbative-quantumchromodynamics (pQCD) calculations. Modification of heavy-flavor production in heavy-ion collisions relative to binary-collision scaling from p + p results, quantified with the nuclear-modification factor (R AA ), provides information on both cold-and hot-nuclear-matter effects. Midrapidity heavy-flavor R AA measurements at the 024909-2 NUCLEAR-MODIFICATION FACTOR FOR OPEN-HEAVY-. . . PHYSICAL REVIEW C 86, 024909 (2012) Relativistic Heavy Ion Collider have challenged parton-energy-loss models and resulted in upper limits on the viscosity-entropy ratio that are near the quantum lower bound. Such measurements have not been made in the forward-rapidity region. Purpose: Determine transverse-momentum (p T ) spectra and the corresponding R AA for muons from heavy-flavor meson decay in p + p and Cu + Cu collisions at √ s NN = 200 GeV and y = 1.65. Method: Results are obtained using the semileptonic decay of heavy-flavor mesons into negative muons. The PHENIX muon-arm spectrometers measure the p T spectra of inclusive muon candidates. Backgrounds, primarily due to light hadrons, are determined with a Monte Carlo calculation using a set of input hadron distributions tuned to match measured-hadron distributions in the same detector and statistically subtracted. Results: The charm-production cross section in p + p collisions at √ s = 200 GeV, integrated over p T and in the rapidity range 1.4 < y < 1.9, is found to be dσ cc /dy = 0.139 ± 0.029 (stat) +0.051 −0.058 (syst) mb. This result is consistent with a perturbative fixed-order-plus-next-to-leading-log calculation within scale uncertainties and is also consistent with expectations based on the corresponding midrapidity charm-production cross section measured by PHENIX. The R AA for heavy-flavor muons in Cu + Cu collisions is measured in three centrality bins for 1 < p T < 4 GeV/c. Suppression relative to binary-collision scaling (R AA < 1) increases with centrality. Conclusions: Within experimental and theoretical uncertainties, the measured charm yield in p + p collisions is consistent with state-of-the-art pQCD calculations. Suppression in central Cu + Cu collisions suggests the presence of significant cold-nuclear-matter effects and final-state energy loss.
