Abstract
An overview is given of the main achievements obtained at the LEAR of CERN in the search for exotic mesons. The impact of these results on the present understanding of the hadronic interaction is outlined. Particular attention is devoted to the discovery of the ‖ 0(1500), the strong candidate for the ground state scalar glueball, and to the definite evidence of the ϱ(1400) , with exotic quantum numbers J PC = 1 −+, which is an excellent candidate for a hybrid meson. The remarkable hypernuclear physics program of DAΦNE, at the Frascati laboratory, and its prospects in exploring fundamental interactions is reviewed, with emphasis on the unique possibility offered to study weak non-mesonic decays of Λ-hypernuclei.
