Recent experimental efforts on hypernuclei at KEK and BNL have been extending the research field of baryon many-body systems in the flavor SU(3) world. Regarding Sigma-hypernuclei, two recent experiments, E887 and E905, at BNL-AGS have drawn important conclusions concerning the narrow-width problem and the bound-state problem of Sigma-hypernuclei based on the high-statistics data of the Be-9(K-,pi(+/-)) and He-4(K-,pi(+/-)) reactions. There has also been an attempt to determine the binding energy of light double-h hypernuclei. These new data on few-body hypernuclear systems may reveal new interesting aspects from the viewpoint of baryon few-body systems.
