Query: The baryon spectrum and the hypercentral Constituent Quark Model   The description of the baryon spectrum is performed using the hypercentral
Consituent Quark Model (hCQM), mainly in comparison with the harmonic
oscillator (h.o.). Recentlly many new states, at various levels of confidence
have been observed, leading to a softening of the missing resonance problem in
the case of positive parity states. However, the number of negative states is
higher that predicted by the commonly used h.o. scheme and therefore one is
forced to take into account also the higher energy shells, which contain an
overall number of states much greater than the observed one. It is shown that,
thanks to the peculiar level scheme of the hCQM, the recently observed negative
parity states can be considered as belonging to the lower shells, keeping the
missing resonance problem within more acceptable limits.
