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 lowenergy 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.
