The principles of minimal sensitivity (PMS) criterion is applied to the perturbative free energy density, or pressure, of hot QCD, which include the ∼ g s ln gs and part of the ∼ g 6 s terms. Applications are made separately to the shortand long-distance parts of the pressure. Comparison with the lattice results, at low temperatures, shows that the resultant “optimal” approximants are substanti...

We show that in a quark model scheme the use of a screened potential, suggested by lattice QCD, instead of an infinitely rising one with the in-terquark distance, provides a more adequate description of the high-energy baryon spectrum. In particular an almost perfect parallelism between the predicted and observed number of states comes out throwing new light about the so-called missing resonanc...
