The traditional motivation for the study is that the absence of flavor singlets in the lowest-lying spectrum is a direct consequence of the color degree of freedom. [The calculation is tested with decuplet baryons Delta(1232) and Omega(1672).] We also analyze decay branching fractions of the flavor-singlet baryon for various masses with the simplest effective Lagrangians.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.102.114032https://journals.aps.org/open access53Chiral dynamicsBound-statesQuark-modelSpectroscopyParticlesMesonQCD.Física (Física)22 Física
