We review the theoretical developments and conceptual advances that stemmed from the
generalization of QCD to the limit of a large number of color charges, originally proposed by't …

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 …

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 …

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 …

We present the first phenomenological study of the masses of orbitally excited baryons in
large Nc QCD. Restricting here to the nonstrange sector of the l= 1 baryons, the 1/Nc …

An extensive and systematic study of the recent η photo-production data up to 1.2 GeV is
presented within a chiral constituent quark model. A model embodying all known nucleonic …

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 …

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 …

Parity-violating elastic electron-proton scattering measures Q weak for the proton, QW p. To
extract QW p from data, all radiative corrections must be well-known. Recently …

We consider the strong decays of the lowest-lying radially excited baryons, in SU (6)
language the states comprising the first excited 56-plet. Assuming a single-quark decay …
