Towards a theory of hadron resonances

M Mai, UG Meißner, C Urbach - Physics Reports, 2023 - Elsevier
In this review, we present the current state of the art of our understanding of the spectrum of
excited strongly interacting particles and discuss methods that allow for a systematic and …

QCD and strongly coupled gauge theories: challenges and perspectives

N Brambilla, S Eidelman, P Foka, S Gardner… - The European Physical …, 2014 - Springer
We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

Quark models of baryon masses and decays

S Capstick, W Roberts - Progress in Particle and Nuclear Physics, 2000 - Elsevier
The application of quark models to the spectra and strong and electromagnetic couplings of
baryons is reviewed. This review focuses on calculations which attempt a global description …

Masses of the Baryons in Large QCD

CL Schat, JL Goity, NN Scoccola - Physical review letters, 2002 - APS
The masses of the negative parity 70-plet baryons are analyzed in large N c QCD to order
1/N c and to first order in SU (3) symmetry breaking. The existing experimental data are well …

Operator analysis of baryon masses in large QCD

CE Carlson, CD Carone, JL Goity, RF Lebed - Physical Review D, 1999 - APS
We consider in detail the mass operator analysis for the nonstrange l= 1 excited baryons in
large N c QCD. We present a straightforward procedure for constructing the large N c baryon …

[HTML][HTML] Analysis of the [56, 2+] baryon masses in the 1/Nc expansion

JL Goity, C Schat, NN Scoccola - Physics Letters B, 2003 - Elsevier
The mass spectrum of the positive parity [56, 2+] baryons is studied in the 1/Nc expansion up
to and including O (1/N c) effects with SU (3) symmetry breaking implemented to first order. A …

Negative parity 70-plet baryon masses in the expansion

JL Goity, CL Schat, NN Scoccola - Physical Review D, 2002 - APS
The masses of the negative parity SU (6) 70-plet baryons are analyzed in the 1/N c
expansion to order 1/N c and to first order in SU (3) breaking. At this level of precision there …

Phenomenology of Large Nc QCD

These lectures are designed to introduce the methods and results of large N c QCD in a
presentation intended for nuclear and particle physicists alike. Beginning with definitions …

Quark model study of the η photo-production: Evidence for a new S11 resonance?

B Saghai, Z Li - The European Physical Journal A-Hadrons and Nuclei, 2001 - Springer
An extensive and systematic study of the recent η photo-production data up to 1.2 GeV is

Quadrupole moments of and in the expansion

AJ Buchmann, JA Hester, RF Lebed - Physical Review D, 2002 - APS
We calculate expressions for the quadrupole moments of nonstrange baryons in which the
number of QCD color charges is N c. Using only the assumption of single-photon exchange …
