Screened potential and the baryon spectrum
arXiv:hep-ph/0312165 · doi:10.1103/PhysRevD.69.074019
Abstract
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 interquark 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 resonance problem.
