All you need is N: Baryon spectroscopy in two large N limits
Aleksey Cherman, Thomas D. Cohen, Richard F. Lebed
The generalization of QCD to many colors is not unique; each distinct choice corresponds to a distinct 1/N_c expansion. The familiar 't Hooft N_c -> \infty limit places quarks in t…
Model Independent Tests of Skyrmions and Their Holographic Cousins
Aleksey Cherman, Thomas D. Cohen, Marina Nielsen
We describe a new exact relation for large QCD for the long-distance behavior of baryon form factors in the chiral limit. This model-independent relation is used to test the…
Interplay of the Chiral and Large N_c Limits in pi N Scattering
Thomas D. Cohen, Richard F. Lebed
Light-quark hadronic physics admits two useful systematic expansions, the chiral and 1/N_c expansions. Their respective limits do not commute, making such cases where both expansio…
