Low-energy antiproton physics at Lear

The present status of the program of low-energy antiproton physics at LEAR is presented. This program is developing according to four main lines: (1) Nucleon-Antinucleon interactions: spectroscopy of protonium and antiprotonic atoms, elastic and inelastic scattering, charge-exchange reactions, strangeness-exchange reactions, antiproton-nucleus interactions. (2) Annihilations: dynamics of nucleon-antinucleon annihilation at rest, multinucleon annihilations, meson spectroscopy, search for exotic structures, proton form factors in the time-like region, study of CP violation. (3) Comparison of p and antip properties: comparison of their inertial masses (test of CPT invariance), and of their gravitational masses. (4) Use of antip as a probe in Atomic Physics
