Excited Heavy Baryon Spectrum in Large N_c Heavy Quark Effective Theory
Jong-Phil Lee🇰🇷 · Chun Liu🇰🇷 · H. S. Song🇰🇷
Abstract
L=1 excited heavy baryon masses are analyzed by heavy quark and large N_c expansions. In heavy quark limit, mass is parameterized by \Lambda-bar and it is expanded further by spin-flavor breaking operators to the zeroth order of 1/N_c. Expanding coefficients will be fixed by more data on the excited baryons in the near future.
