Heavy baryon masses in the 1/{ital m}{sub {ital Q}} and 1/{ital N}{sub {ital c}} expansions
- Department of Physics, University of California at San Diego, La Jolla, California 92093 (United States)
The masses of baryons containing a single heavy quark are studied in a combined expansion in 1/{ital m}{sub {ital Q}}, 1/{ital N}{sub {ital c}}, and SU(3) flavor symmetry breaking. Heavy quark baryon mass splittings are related to mass splittings of the octet and decuplet baryons. The {Sigma}{sub {ital c}}{sup {asterisk}}, {Xi}{sub {ital c}}{sup {prime}}, and {Omega}{sub {ital c}}{sup {asterisk}} are predicted to the level of a few MeV. A number of bottom baryon mass splittings are predicted very accurately. {copyright} {ital 1996 The American Physical Society.}
