“…While for charmonium there are clear indications for the presence of a regeneration components in the observed yields [15], no such signals have been firmly established for bottomonium yet. One hint toward the onset of regeneration could be the small change in the bottomonium suppression when going from 2.76 to 5.02 TeV.…”

Bottomonium suppression using a lattice QCD vetted potential

We estimate bottomonium yields in relativistic heavy-ion collisions using a lattice QCD vetted, complex-valued, heavy-quark potential embedded in a realistic, hydrodynamically evolving medium background. We find that the lattice-vetted functional form and temperature dependence of the proper heavy-quark potential dramatically reduces the dependence of the yields on parameters other than the temperature evolution, strengthening the picture of bottomonium as QGP thermometer. Our results also show improved agreement between computed yields and experimental data produced in RHIC 200 GeV=nucleon collisions. For LHC 2.76 TeV=nucleon collisions, the excited states, whose suppression has been used as a vital sign for quark-gluon-plasma production in a heavy-ion collision, are reproduced better than previous perturbatively-motivated potential models; however, at the highest LHC energies our estimates for bottomonium suppression begin to underestimate the data. Possible paths to remedy this situation are discussed.

“…Measurements of charmonium yields e.g. have shown that for this lighter flavor indeed regeneration becomes quite important at LHC energies [15]. For bottomonium, only recently have there been studies carried out that include a regeneration component, see e.g.…”

“…Toward this end, we employ our previously developed semiclassical Boltzmann/rate equation approach which has been extensively tested by a wide variety of quarkonium observables from SPS via RHIC to LHC energies for both charmonia and bottomonia [27,[39][40][41]. Its results are largely consistent with other semi-classical approaches [28,30,[42][43][44][45][46][47], although quantitative cross comparisons under controlled conditions remain to be carried out [9]. Furthermore, the effects of explicit quantum evolution equations for quarkonia are receiving increased attention [48][49][50][51][52].…”

The in-medium color potential is a fundamental quantity for understanding the properties of the strongly coupled quark-gluon plasma (sQGP). Open and hidden heavy-flavor (HF) production in ultrarelativistic heavy-ion collisions (URHICs) has been found to be a sensitive probe of this potential. Here we utilize a previously developed quarkonium transport approach in combination with insights from open HF diffusion to extract the color-singlet potential from experimental results on Υ production in URHICs. Starting from a parameterized trial potential, we evaluate the Υ transport parameters and conduct systematic fits to available data for the centrality dependence of ground and excited states at RHIC and the LHC. The best fits and their statistical significance are converted into a temperature dependent potential. Including nonperturbative effects in the dissociation rate guided from open HF phenomenology, we extract a rather strongly coupled potential with substantial remnants of the long-range confining force in the QGP.

“…Quarkonium (bound heavy quark-antiquark states) are an intriguing probe of the quark-gluon plasma [1]. Originally proposed by Matsui and Satz [2], the suppression of quarkonia has remained an active topic of experimental [3][4][5][6][7][8] and theoretical [9][10][11][12][13][14][15] investigation ever since. The central idea is that a thermal medium tends to break up quarkonium bound states; one then investigates how strong this effect is expected to be theoretically, and how much such states are suppressed experimentally.…”

Brambilla, Escobedo, Soto, and Vairo have derived an effective description of quarkonium with two parameters; a momentum diffusion term and a real self-energy term. We point out that the real self-energy term can be expressed directly in terms of Euclidean electric field correlators along a Polyakov line. This quantity can be directly studied on the lattice without the need for analytical continuation. We show that existing Minkowski-space calculations of this correlator correspond with the known NLO Euclidean value of the relevant electric field two-point function.
