Hypernuclei and interactions of kaons with nuclei

Recent experimental and theoretical progress in hypernuclear physics is reviewed. Different models for hyperon-nucleus central and spin-orbit potentials are compared: several models yield a very small spin-orbit strength for the ..lambda.., as experimentally observed, but differ considerably in their predictions for the ..sigma... The new data on the /sup 13/C hypernuclear spectrum, as obtained in the (K/sup -/, ..pi../sup -/) strangeness exchange reaction at 800 MeV/c, are discussed. It is shown how one extracts constraints on the ..lambda..-nucleus and effective ..lambda..-nucleon ineractions from the data. The new BNL data on the (K/sup -/, ..pi../sup +/) reaction at 720 MeV/c, leading to ..sigma..-hypernuclear states, are examined. The case of /sup 6/Li(K/sup -/, ..pi../sup +/)/sup 6/H is discussed in some detail, and some speculations concerning the (K/sup -/, ..pi../sup +/) reaction on other targets are presented. The physical mechanisms which may lead to unusually narrow ..sigma.. excitations in some systems are examined. Finally, the physics motivations for several future hypernuclear experiments which are already under development, such as (K/sup -/, ..pi../sup -/..gamma..) and ..pi../sup + -/, K/sup +/) studies, or under preliminary consideration, for instance, the (K/sup -/, K/sup +/) reaction producing S=-2 hypernuclei are reviewed.
