Cornell Potential Parameters for S-Wave Heavy Quarkonia

S-Wave Quarkonia in Potential Models

For the last twenty years the melting of heavy quark bound states has been considered an unambiguous signal for deconfinement [1]. Understanding the modification of the properties of heavy quarkonia in a hot medium is therefore essential for understanding deconfinement. Phenomenological studies based on potential models have been recently accompanied by lattice QCD calculations. The temperature...

Semirelativistic potential model for heavy quarkonia.

Heavy Quarkonia Survival in Potential Model

We investigate the quarkonia correlators in QCD with no light quarks within a potential model with different screened potentials. Our results for the temperature dependence of the charmonium and bottomonium correlators are qualitatively consistent with existing and preliminary lattice results. We identify however, a much reacher structure in the correlators than the one seen on the lattice. PAC...

Heavy quark potential and quarkonia dissociation rates

Quenched lattice data for the QQ̄ interaction (in terms of heavy quark free energies) in the color singlet channel at finite temperatures are fitted and used within the nonrelativistic Schrödinger equation formalism to obtain binding energies and scattering phase shifts for the lowest eigenstates in the charmonium and bottomonium systems in a hot gluon plasma. The partial dissociation rate due t...

Heavy Quarkonia

Recent experimental results on heavy quarkonia spectroscopy and decays are reviewed. In particular, new results are discussed on charmonium spin singlet states, bottomonium D-states, photon and hadronic transitions from heavy quarkonium states, and the unexplained narrow X(3872) state.
