Lambda hypernucleus which contains s-quark in addition to normal u, d-quarks, is a powerful tool to study baryon interaction and structure of deep inside of nucleus. In 80-90s, experiments of Lambda hypernuclei with meson beams were intensively performed at BNL and KEK. Thanks to a high quality electron beam at JLab CEBAF, the study of hypernuclei with an electron beam started in 2000. ...

The knowledge on $K^-$ absorption by light nuclei is still rather incomplete because of the lack of experimental data, but has recently gained a fresh boost. New precision experiments have been performed, mainly with the aim of finding signatures of multibaryon strange aggregates (dubbed "bound kaonic nuclear clusters"), which could be formed following the absorption of the kaon....

We review the strangeness production data in heavy-ion collisions at energies arround the NN production threshold. The dense nuclear matter environment produced in heavy-ion collisions provides unique opportunities to form strange few body systems. In search for those systems with strong decays special emphasis will be given to $\Lambda$ p and $\Lambda$ d correlations. Long lived weakly...

The recent determination of Lambda-nucleon spin-dependent interaction matrix elements in Lambda hypernuclei [1] from comprehensive measurements of gamma ray transitions [2] provides accurate estimates of Lambda-Lambda separation energies in double-Lambda hypernuclei across the nuclear p shell. Here we outline a shell-model approach [3] to evaluate the consistency of the world emulsion...
