Heavy Quarkonia and Quark Drip Lines in Quark-Gluon Plasma
Using the potential model and thermodynamical quantities obtained in lattice gauge calculations, we determine the spontaneous dissociation temperatures of color-singlet quarkonia and the ‘quark drip lines’ which separate the region of bound QQ̄ states from the unbound region. The dissociation temperatures of J/ψ and χb in quenched QCD are found to be 1.62Tc and 1.18Tc respectively, in good agree...
متن کاملDissociation of Heavy Quarkonia in the Quark-Gluon Plasma
Using a temperature-dependent potential obtained from lattice gauge calculations, we study the stability of heavy quarkonia in the quark-gluon plasma. We find that only Υ(1S) and ηb(1S) are bound in the quark-gluon plasma, and have a small binding energy. The quark-gluon plasma may be revealed by an Υ(1S) dilepton peak with an invariant mass close to twice the current b quark mass, which is low...
متن کاملQuarkonia and Quark Drip Lines in Quark-Gluon Plasma
We extract the Q-Q̄ potential by using the thermodynamic quantities obtained in lattice gauge calculations. The potential is tested and found to give dissociation temperatures that agree well with those from lattice gauge spectral function analysis. Using such a Q-Q̄ potential, we examine the quarkonium states in a quark-gluon plasma and determine the ‘quark drip lines’ which separate the region ...
متن کاملTransport properties and Langevin dynamics of heavy quarks and quarkonia in the Quark Gluon Plasma
Quark Gluon Plasma transport coefficients for heavy quarks and QQ pairs are computed through an extension of the results obtained for a hot QED plasma by describing the heavy-quark propagation in the eikonal approximation and by weighting the gauge field configurations with the Hard Thermal Loop effective action. It is shown that such a model allows to correctly reproduce, at leading logarithmi...
متن کاملHeavy Quarks in the Quark-gluon Plasma
Heavy-flavor particles are believed to provide valuable probes of the medium produced in ultrarelativistic collisions of heavy nuclei. In this article we review recent progress in our understanding of the interactions of charm and bottom quarks in the Quark-Gluon Plasma (QGP). For individual heavy quarks, we focus on elastic interactions for which the large quark mass enables a Brownian motion ...
