[Theory-seminars] Theory Seminar - Wed. 20th | Cintia Willemyns

[Andrea Signori]

Dear all,

this week there will be only one seminar.
We tried to minimize the clash with the Users’ Group Meeting: due to the lack of available rooms after the UGM, the talk has been scheduled on Wednesday 20th at 1pm. Details below:

Theory Seminar
Wednesday, June 20
1:00pm - CEBAF Center, Room L102

Cintia Willemyns (CONICET)
Baryons of the N=2 quark model band in the large Nc limit

The link to attend remotely via BlueJeans is available at https://www.jlab.org/div_dept/theory/seminars/2018-spring-theory-seminar.html <https://www.jlab.org/div_dept/theory/seminars/2018-spring-theory-seminar.html>  
Looking forward to seeing you on Wednesday,

Abstract:

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.
