Antiproton physics in the next decade

Notes from a talk at the LAMPF II workshop are given. Topics include antinucleon physics in the next decade - the role of anti p and anti n beams in shedding light on some fundamental problems in nuclear and particle physics. Some particle aspects considered include; a) anti n as a source of antiquarks (anti NN provides a well-suited entrance channel for formation of new kind of mesons), and b) possibility of forming quark-gluon phase in anti N annihilations in nuclei. Some nuclear aspects discussed include: a) medium and long range parts of NN and anti NN potentials related by G-parity, b) search for coherent tensor forces in anti NN spin observables, and c) quasi-molecular resonance phenomena in anti NN and anti N-nucleus systems.
