The Workshop on Physics at LEAR with Low Energy Cooled Anti- protons was held in Erice, May 9 - 16, 1982, at the Ettore Majorana Centre for Scientific Culture, in the framework of the International School of Physics of Exotic Atoms. The Workshop was organized by a committee composed of R. Armenteros, D. Bugg, P. Dalpiaz, U. Gastaldi, K. Kilian, R. Klapisch, P. Lefevre, D. M6hl, S. Polikanov, B. Povh and J.M. Richard. It was attended by 101 physicists from 44 insti- tutions and 14 countries, representing one third of the LEAR users. Thjs Workshop was the first general meeting of the LEAR commu- nity after the approval of the CERN Low Energy Antiproton Ring faci- lity and of the experiments scheduled there for the initial period of oper&tion. It was organized for three main purposes: (i) to review the field of low energy antiproton physics, the initial LEAR experimental programme and the status of preparation of the approved experiments; (ii) to review the facility and the progress in its construction, and to discuss the conditions of its operation; (iii) to discuss future developments of the facility and of the experi- mental programme. These Proceedings contain the papers presented in Erice both orally and in the poster session, which displayed also contributions from colleagues who unfortunately could not attend the Workshop. The reports have been ordered in four sessions, following the pro- gramme of the meeting. The CERN low energy antiproton facility is presented in Section I.

The second course of the International School on Physics with Low Energy Antiprotons was held in Erice, Sicily at the Ettore Majorana Centre for Scientific Culture, from May 20 to May 31, 1987. The School is dedicated to physics accessible to experiments using low energy antiprotons, especially in view of operation of the LEAR facility at CERN with the upgraded antiproton source AAC (Antiproton Accumulator AA and Antiproton Collector ACOL). The first course in 1986 covered topics related to fundamental symmetries. This book contains the proceedings of the second course which focused on spectroscopy of light and heavy quarks. These proceedings contain both the tutorial lectures and contri butions presented by participants during the School. The papers are organized in four sections: The first section includes theoretical reviews. Section II contains experimental reviews and covers the results in meson spectroscopy from DM2, MARK III, GAMS and n-WA76. Section III presents the new meson spectroscopy experiments in pre paration at CERN and Fermilab: Crystal Barrel, OBELIX, Jetset and E760. Section IV is dedicated to LEAR and to future facilities where meson spectroscopy would be a principal component of the physics programme. We should like to thank Dr. Alberto Gabriele and the staff of the Ettore Majorana Centre who provided for a smooth running of the School and a very pleasant stay. We are particularly grateful to Mrs. Anne Marie Bugge for her crucial help during the preparation and running of the School and for the editing of these Proceedings."
