### Baryons of the N=2 quark model band in the large Nc limit

#### Cintia Willemyns (CNEA - CONICET)

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 connexion 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.

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 [20, 1+]. In this

analysis, we included configuration mixing effects.
