Operator Analysis of L=1 Baryon Masses in Large N_c QCD
Carl E. Carlson, Christopher D. Carone, Jose L. Goity +1
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 bary…
Phenomenology of Large N_c QCD
Richard F. Lebed
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 a…
NN Interactions in QCD: Old and New Techniques
Richard F. Lebed
Since QCD is believed to be the underlying theory of the strong interaction, it is appropriate to study techniques that take into account more features of its rich and complex stru…
Explicit Quark-Hadron Duality in 1+1 Dimensions
Richard F. Lebed
Explicit quark-hadron duality in the limit of heavy quark mass is studied using the 't Hooft model, where both partonic and hadronic amplitudes may be computed exactly. Results for…
Masses of Orbitally Excited Baryons in Large N_c QCD
Carl E. Carlson, Christopher D. Carone, Jose' L. Goity +1
We present the first phenomenological study of the masses of orbitally excited baryons in large N_c QCD. Restricting here to the nonstrange sector of the L=1 baryons, the 1/N_c exp…
Quark-Hadron Duality in the 't Hooft Model for Meson Weak Decays: Different Quark Diagram Topologies
Benjamin Grinstein, Richard F. Lebed
We compare the effects of different quark diagram topologies on the weak hadronic width of heavy-light mesons in the large N_c limit. We enumerate the various topologies and show t…
New Constraints on Dispersive Form Factor Parameterizations from the Timelike Region
W. W. Buck, Richard F. Lebed
We generalize a recent model-independent form factor parameterization derived from rigorous dispersion relations to include constraints from data in the timelike region. These cons…
