<span class=""><div class=""><span style="font-size: 14px;" class="">Baryon spectroscopy has been essential for our understanding of QCD in the low-energy regime.
The quark model has since long time been a useful tool to analyze the spectrum and properties of
excited baryons. Recent studies of lattice QCD calculations seem to confirm the quark model
classification scheme, strongly suggesting a connection between QCD and the quark model. The
generalization of QCD to Nc colors has proven to be a powerful analytical method for studying the
behavior of strong interaction physics. There is an explicit relation between the quark model symmetries
and the QCD symmetries in the large Nc limit, in this sense large Nc QCD provides important insight into
the success of the quark model.
</span></div><span style="font-size: 14px;" class="">I will present the results of a complete analysis of the spectrum of all the states in the N=2 quark model band
with Nf=3 in the large Nc limit including the often disregarded antisymmetric multiplet </span></span><span style="font-size: 14px;" class="">[20, 1+]. In this analysis,
we included configuration mixing effects.</span></span><span class=""></span></font></pre>
