N2 - We show that in a quark model scheme the use of a screened potential, suggested by lattice QCD, instead of one infinitely rising 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 on the so-called missing resonance problem.
