Quarkonium Spectral Functions
In this talk I summarize the progress achieved in recent years on the understanding of quarkonium properties at finite temperature. Theoretical studies from potential models, lattice QCD, and effective field theories are discussed. I also highlight a bridge from spectral functions to experiment.
متن کاملGround State Quarkonium Spectral Functions Above Deconfinement
We discuss the temperature-dependence of S-wave quarkonium spectral functions in a nonrelativistic Green’s function approach and compare these to lattice QCD results.
متن کاملRealizing the Potential of Quarkonium
I recall the development of quarkonium quantum mechanics after the discovery of Υ. I emphasize the empirical approach to determining the force between quarks from the properties of cc̄ and bb̄ bound states. I review the application of scaling laws, semiclassical methods, theorems and near-theorems, and inverse-scattering techniques. I look forward to the next quarkonium spectroscopy in the Bc sys...
متن کاملSome Results on Convex Spectral Functions: I
In this paper, we give a fundamental convexity preserving for spectral functions. Indeed, we investigate infimal convolution, Moreau envelope and proximal average for convex spectral functions, and show that this properties are inherited from the properties of its corresponding convex function. This results have many applications in Applied Mathematics such as semi-definite programmings and eng...
متن کاملQuarkonium wave functions at the origin.
We tabulate values of the radial Schrödinger wave function or its first nonvanishing derivative at zero quark-antiquark separation, for cc̄, cb̄, and bb̄ levels that lie below, or just above, flavor threshold. These quantities are essential inputs for evaluating production cross sections for quarkonium states. PACS numbers: 14.40Gx, 13.20Gd, 13.25Gv Typeset using REVTEX Internet address: eichten@f...
