Title: Approach to equilibrium of quarkonium in quark-gluon plasma

Abstract

We calculate the dissociation and recombination rates of $$\mathrm{{\Upsilon}}(1S)$$ in quark-gluon plasma by using potential nonrelativistic QCD. We then study the dynamical in-medium evolution of the $$b\overline{b}{-}\mathrm{{\Upsilon}}$$ system in a periodic box via the Boltzmann equation and explore how the system reaches equilibrium. We find that interactions between the free heavy quarks and the medium are necessary for the system to reach equilibrium. We find that the angular distribution of $$\mathrm{{\Upsilon}}(1S)$$ probes the stages at which recombination occurs. Finally, we study the system under a longitudinal expansion and show that different initial conditions evolve to distinct final ratios of hidden and open $$b$$ flavors. We argue that experimental measurements of the ratio could address open questions in the quarkonium production in heavy ion collisions.

Coupled Boltzmann transport equations of heavy quarks and quarkonia in quark-gluon plasma

Journal Article Yao, Xiaojun ; Ke, Weiyao ; Xu, Yingru ; ... - Journal of High Energy Physics (Online)

We develop a framework of coupled transport equations for open heavy flavor and quarkonium states, in order to describe their transport inside the quark-gluon plasma. Our framework is capable of studying simultaneously both open and hidden heavy flavor observables in heavy-ion collision experiments and can account for both, uncorrelated and correlated recombination. Our recombination implementation depends on real-time open heavy quark and antiquark distributions. We carry out consistency tests to show how the interplay among open heavy flavor transport, quarkonium dissociation and recombination drives the system to equilibrium. We then apply our framework to study bottomonium production in heavy-ion collisions.more »« less

Quarkonium in-medium transport equation derived from first principles

Journal Article Yao, Xiaojun ; Mehen, Thomas - Physical Review. D.

We use the open quantum system formalism to study the dynamical in-medium evolution of quarkonium. The system of quarkonium is described by potential nonrelativistic QCD while the environment is a weakly coupled quark-gluon plasma in local thermal equilibrium below the melting temperature of the quarkonium. Under the Markovian approximation, it is shown that the Lindblad equation leads to a Boltzmann transport equation if a Wigner transform is applied to the system density matrix. Our derivation illuminates how the microscopic time reversibility of QCD is consistent with the time-irreversible in-medium evolution of quarkonium states.

Quarkonium inside the quark-gluon plasma: Diffusion, dissociation, recombination, and energy loss

Journal Article Yao, Xiaojun ; Müller, Berndt - Physical Review. D.

We consider the quarkonium diffusion, dissociation, and recombination inside quark-gluon plasma. We compute scattering amplitudes in potential nonrelativistic QCD for relevant processes. These processes include the gluon absorption/emission at the order gr, inelastic scattering at the order g²r, and elastic scattering with medium constituents at the order g²r². We show these amplitudes satisfy the Ward identity. We also consider one-loop corrections. The dipole interaction between the color singlet and octet is not running at the one-loop level. Interference between the tree-level gluon absorption/emission and its thermal loop corrections cancels the collinear divergence in the t -channel inelastic scattering. The inelasticmore »« less

Quarkonium production in heavy ion collisions: coupled Boltzmann transport equations

Journal Article Yao, Xiaojun ; Ke, Weiyao ; Xu, Yingru ; ... - Nuclear Physics. A

We develop a set of coupled Boltzmann equations to describe the dynamical evolution of heavy quarks and quarkonia inside the quark-gluon plasma. The quarkonium dissociation and recombination terms are calculated from pNRQCD. Their interplay drives the system to a detailed balance. The heavy quark energy loss term is necessary for the system to reach kinematic thermalization. By coupling the transport equations with initial particles' momenta generated by PYTHIA and hydrodynamic medium evolutions, we can describe the RAA ofmore »« less

Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction

Journal Article Yao, Xiaojun ; Mehen, Thomas - Journal of High Energy Physics (Online)

We study quarkonium transport in the quark-gluon plasma by using the potential nonrelativistic QCD (pNRQCD) effective field theory and the framework of open quantum systems. We argue that the coupling between quarkonium and the thermal bath is weak using separation of scales, so the initial density matrix of the total system factorizes and the time evolution of the subsystem is Markovian. We derive the semiclassical Boltzmann equation for quarkonium by applying a Wigner transform to the Lindblad equation and carrying out a semiclassical expansion. We resum relevant interactions to all orders in the coupling constant at leading power of themore »« less
