Strong and Weak Interactions of Strange Hadrons

Abstract

I review hadronic processes involving strange hadrons, especially hyperons from the quark structure point of view. The strong interaction of quarks expects several important new features when the strangeness is introduced upon the non-strange degrees of freedom. I concentrate on the instanton induced interaction, effects of the Pauli principle for strangeness and the nonleptonic weak interaction of strangeness. The single hadron as well as the two baryon systems including the $H$ dibaryon and other exotic hadronic systems with strangeness are studied in this context.
