“…We reconstruct σ tot 1S using the di-muon branching ra- [28], i.e., σ pp→bb =3.2 µb, with a factor of 0.52 to obtain σ pp→bb =1.67µb in one fireball (∆y=1.8), or dσ pp→bb dy =0.92 µb. This is consistent with the most recent PHENIX results [55]. For simplicity, we use the same input values for uranium-uranium (U-U) collisions at 193 GeV.…”

Color screening and regeneration of bottomonia in high-energy heavy-ion collisions

2017

View full text Add to dashboard Cite

The production of ground-state and excited bottomonia in ultrarelativistic heavy-ion collisions is investigated within a kinetic-rate equation approach including regeneration. We augment our previous calculations by an improved treatment of medium effects, with temperature-dependent binding energies and pertinent reaction rates, B-meson resonance states in the equilibrium limit near the hadronization temperature, and a lattice-QCD based equation of state for the bulk medium. In addition to the centrality dependence of the bottomonium yields we compute their transverse-momentum (pT ) spectra and elliptic flow with momentum-dependent reaction rates and a regeneration component based on b-quark spectra from a nonperturbative transport model of heavy-quark diffusion. The latter has noticeable consequences for the shape of the bottomonium pT spectra. We quantify how uncertainties in the various modeling components affect the predictions for observables. Based on this we argue that the Υ(1S) suppression is a promising observable for mapping out the in-medium properties of the QCD force, while Υ(2S) production can help to quantify the role of regeneration from partially thermalized b quarks.

Open charm and dileptons from relativistic heavy-ion collisions

et al. 2018

View full text Add to dashboard Cite

Dileptons are considered as one of the cleanest signals of the quark-gluon plasma (QGP), however, the QGP radiation is masked by many 'background' sources from either hadronic decays or semileptonic decays from correlated charm pairs. In this study we investigate the relative contribution of these channels in heavy-ion collisions from √ sNN = 8 GeV to 5 TeV with a focus on the competition between the thermal QGP radiation and the semileptonic decays from correlated D−meson pairs. As a 'tool' we employ the parton-hadron-string dynamics (PHSD) transport approach to study dilepton spectra in Pb+Pb (Au+Au) collisions in a wide energy range incorporating for the first time a fully microscopic treatment of the charm dynamics and their semileptonic decays. We find that the dileptons from correlated D−meson decays dominate the 'thermal' radiation from the QGP in central Pb+Pb collisions at the intermediate masses (1.2 GeV < M < 3 GeV) for √ sNN > 40 GeV, while for √ sNN = 8 to 20 GeV the contribution from D,D decays to the intermediate mass dileptonspectra is subleading such that one should observe a rather clear signal from the QGP radiation. We, furthermore, study the pT -spectra and the RAA(pT ) of single electrons at different energies as well as the excitation function of the inverse slope of the mT -spectra for intermediate-mass dileptons from the QGP and from charm decays. We find moderate but characteristic changes in the inverse slope parameter for √ sNN > 20 GeV which can be observed experimentally in high statistics data.Additionally, we provide detailed predictions for dilepton spectra from Pb+Pb collisions at √ sNN = 5.02 TeV.

“…The role of small colliding system (p-A/d-A collisions) has recently received renewed interest at RHIC and the LHC, including the quarkonium sector [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. A moderate J/ψ suppression (enhancement) has been found in both d-Au collisions at RHIC and forward (backward) rapidity p-Pb collisions at the LHC, largely consistent with CNM effects (most notably a nuclear anti-/shadowing of the initial parton distribution functions) [24][25][26][27][28][29].…”

In-medium charmonium production in proton-nucleus collisions

We study charmonium production in proton-nucleus (p-A) collisions focusing on final-state effects caused by the formation of an expanding medium. Toward this end we utilize a rate equation approach within a fireball model as previously employed for a wide range of heavy-ion collisions, adapted to the small systems in p-A collisions. The initial geometry of the fireball is taken from a Monte-Carlo event generator where initial anisotropies are caused by fluctuations. We calculate the centrality and transversemomentum dependent nuclear modification factor (R pA ) as well as elliptic flow (v 2 ) for both J/ψ and ψ(2S) and compare them to experimental data from RHIC and the LHC. While the R pA s show an overall fair agreement with most of the data, the large v 2 values observed in p-Pb collisions at the LHC cannot be accounted for in our approach. While the former finding generally supports the formation of a near thermalized QCD medium in small systems, the discrepancy in the v 2 suggests that its large observed values are unlikely to be due to the final-state collectivity of the fireball alone.
