Vol. 754 (2005), pp. 212C-220C. - Amsterdam : Elsevier B.V., 2005 Keywords jadrová fyzika nuclear physics Narrow Baryon Resonances Language English Country Netherlands Annotation We study the quark-mass dependence of J(P) = (1/2-) s-wave and J(P) = 3/2(-) d-wave baryon resonances. Parameter-free results are obtained in terms of the leading order chiral Lagrangian. In the 'heavy' SU(3) limit with m(pi) = m(K) similar or equal to 500 MeV the s-wave resonances turn into bound states forming two octets plus a singlet representations of the SU(3) group. Similarly the d-wave resonances turn into bound states forming an octet and a decuplet in this limit. A contrasted result is obtained in the 'light' SU(3) limit with m(pi) = M-K similar or equal to 140 MeV for which no resonances exist. Public work category ADC No. of Archival Copy 8629 Catal.org.
