Diquark Correlations from Nucleon Charge Radii
Carl E. Carlson, Christopher D. Carone, Herry J. Kwee +1
We argue that precise measurements of charge and magnetic radii can meaningfully constrain diquark models of the nucleon. We construct properly symmetrized, nonrelativistic three-q…
On the Existence of Heavy Pentaquarks: The large Nc and Heavy Quark Limits and Beyond
Thomas D. Cohen, Paul M. Hohler, Richard F. Lebed
We present a very general argument that the analogue of a heavy pentaquark (a state with the quantum numbers of a baryon combined with an additional light quark and a heavy antiqua…
The 1/N_c Approach for Baryon Resonances
Richard F. Lebed
I give a brief overview of the model-independent analysis of unstable baryon resonances in the 1/N_c QCD expansion. This approach produces numerous surprising semi-quantitative phe…
Phenomenology of the Baryon Resonance 70-plet at Large N_c
Thomas D. Cohen, Richard F. Lebed
We examine the multiplet structure and decay channels of baryon resonances in the large N_c QCD generalization of the N_c = 3 SU(6) spin-flavor 70. We show that this ``70'', while…
SU(3) Baryon Resonance Multiplets in Large N_c QCD
Thomas D. Cohen, Richard F. Lebed
We extend the recently developed treatment of baryon resonances in large N_c QCD to describe resonance multiplets collected according to the SU(3) flavor symmetry that includes str…
Baryon Resonances in the 1/N_c Expansion
Richard F. Lebed
The 1/N_c expansion of QCD provides a valuable semiquantitative tool to study baryon scattering amplitudes and the short-lived baryon resonances embedded within them. A generalizat…
