Baryon Chiral Perturbation Theory in Partially Quenched Large-Nc QCD
Chi-Keung Chow, Soo-Jong Rey
Baryons of lower spin in partially quenched large- QCD are studied with particular emphasis to interpolation between standard unquenched and fully quenched limits. In large $N…
Qualitative Aspects of Polarization Distributions In Excited Heavy Hadron Productions
Chi-Keung Chow
Within the context of flux tube models, heavy quark fragmentation takes place through the breaking of flux tubes with the production of a (di)quark-anti(di)quark pair. It is found…
Spin Symmetry Without Heavy Quarks: Hyperon Form Factors In The Large Limit
Chi-Keung Chow
In the large limit, all hyperon decays involving the same quark diagram are described by a single weak form factor . No assumption on the mass of or…
Heavy Baryons and Multiquark Exotics in the Large limit
Chi-Keung Chow
In the large limit, one can describe normal heavy baryons and heavy pentaquarks as bound states of heavy mesons to chiral (anti)solitons. In this picture,…
