Exploring QCD: from LEAR to GSI

Abstract

In this invited contribution I briefly review some of the principal topics in hadron spectroscopy that were studied at the CERN low-energy antiproton facility LEAR, from its beginnings in the early 1980s to the present. These topics include the nature of multiquark systems, the short-ranged nuclear force, and gluonic hadrons, including glueballs and hybrids. Lessons we have learned from the LEAR program that are relevant to the future GSI project are given particular emphasis.
