Scaling Relations in Phenomenology of QCD Sum Rules for Heavy Quarkonium

In the framework of a specific scheme of the QCD sum rules for S-wave levels of the heavy quarkonium, one derives expressions, relating the leptonic constants, the energetic density of quarkonium states and universal characteristics in the heavy quarkonium physics, such as the difference between the masses of heavy quark Q and meson (Qq̄) and the number of heavy quarkonium levels below the thres...

Quarkonium Suppression

I discuss quarkonium suppression in equilibrated strongly interacting matter. After a brief review of basic features of quarkonium production I discuss the application of recent lattice data on the heavy quark potential to the problem of quarkonium dissociation as well as the problem of direct lattice determination of quarkonium properties in finite temperature lattice QCD.

Quarkonium Production

Molecular Quarkonium

It has been pointed out long time ago [1] that there should exist bound and/or resonant states of heavy hadrons, dubbed ‘molecular’ and arising due to the strong force between the light constituents of the heavy hadrons. Indeed, considering the interaction between a heavy meson, consisting of a heavy quark Q and a light antiquark q̄, and an antimeson (Q̄q), it is clear that there is a normal stro...
