“…By taking different ansätze for ω 2 (T ), we show that the THO model can describe the behavior of the measured J/ψ yield over the expected CNM effects R AA /R AA (CNM), as a function of the multiplicity of charged particles. Our method can be applied to more realistic cases, even for a QQ Hamiltonians containing a complex confinement potential as the ones given in [51,52] which are in good agreement with LQCD.…”

“…The latter, besides screening, displays also an imaginary part related to collisions [49,50]. The determination of this imaginary part also provides insight into how the anisotropy of the medium relates with the width of the states [51,52]. The use of complex potentials for describing data of charmonium suppression in pp and pA collisions has been documented in [53,54,55,56].…”

We discuss the interplay of screening, absorption and regeneration effects, on the quantum mechanical evolution of quarkonia states, within a time-dependent harmonic oscillator (THO) model with complex oscillator strength. We compare the results with data for R AA /R AA (CNM) from CERN and RHIC experiments. In the absence of a measurement of cold nuclear matter (CNM) effects at LHC we estimate their role and interpret the recent data from the ALICE experiment. We also discuss the temperature dependence of the real and imaginary parts of the oscillator frequency which stand for screening and absorption/regeneration, respectively. We point out that a structure in the J/ψ suppression pattern for In-In collisions at SPS is possibly related to the recently found X(3872) state in the charmonium spectrum. Theoretical support for this hypothesis comes from the cluster expansion of the plasma Hamiltonian for heavy quarkonia in a strongly correlated medium.

“…In our formalism, we have approximated the quarkonium wavefunction by the vacuum wavefunction, which is valid if the thermal effects on the quarkonium wavefunctions are small. The thermal wavefunctions (for example, those obtained by solving the Schrödinger equation with thermal potentials [2,[8][9][10]) will be wider in position space at higher temperature and therefore will dissociate more easily. Therefore a stronger suppression at LHC could be the evidence for thermalization effects at the level of the quarkonium wavefunction.…”

“…This picture suggests that it may be possible to observe sequential melting of narrower quarkonia as we explore thermal media of increasing temperatures [3,4]. Several studies (see [5] for a recent review) have calculated the modification of quarkonium yields in collisions at SPS, RHIC, and the LHC [6][7][8][9][10][11].…”

“…For a quarkonium which is stationary or slowly moving through the thermal medium it might be safe to assume that it reaches thermal equilibrium with the medium. In this picture, the wavefunction of the quarkonium (the lowest Fock component) is better described by the solution of the Schrödinger equation with a modified potential that depends on the temperature [2,[8][9][10]. The potentials used are based on finite temperature lattice calculations of the potential between two static charges [33].…”

High transverse momentum quarkonium production and dissociation in heavy ion collisions

2013

View full text Add to dashboard Cite

We calculate the yields of quarkonia in heavy ion collisions at RHIC and the LHC as a function of their transverse momentum. Based upon non-relativistic quantum chromodynamics, our results include both color-singlet and color-octet contributions and feed-down effects from excited states. In reactions with ultra-relativistic nuclei, we focus on the consistent implementation of dynamically calculated nuclear matter effects, such as coherent power corrections, cold nuclear matter energy loss, and the Cronin effect in the initial state. In the final state, we consider radiative energy loss for the color-octet state and collisional dissociation of quarkonia as they traverse through the QGP. Theoretical results are presented for J/ψ and Υ and compared to experimental data where applicable. At RHIC, a good description of the high-pT J/ψ modification observed in central Cu+Cu and Au+Au collisions can be achieved within the model uncertainties. We find that measurements of J/ψ yields in proton-nucleus reactions are needed to constrain the magnitude of cold nuclear matter effects. At the LHC, a good description of the experimental data can be achieved only in mid-central and peripheral Pb+Pb collisions. The large five-fold suppression of prompt J/ψ in the most central nuclear reactions may indicate for the first time possible thermal effects at the level of the quarkonium wavefunction at large transverse momenta.
