"GSI-Colloquium:"Contemporary Topics in Strangeness Nuclear Physics"

In this talk I will discuss the progress made both experimentally and theoretically towards understanding the physics of hypernuclei, that is nuclear systems that include one or more strange baryons known as hyperons, mostly the Lambda(1116) lightest one, and which live sufficiently long, of order pico-seconds, to be explored in dedicated experiments. Some topical issues will be highlighted: light neutron-rich hypernuclei, the `hyperon puzzle' in neutron stars, and the possible existence of a doubly-strange dibaryon known as Jaffe's H dibaryon. Time-permitting, I will also talk on antikaon-nuclear interactions and the search for antikaon-nuclear quasibound states, including the issue of `antikaon condensation'.
