Double strangeness production, i.e. the net production of two s quarks and two s quarks (carried inside hadrons) in antiproton-nucleus annihilations is investigated theoretically. The various mechanisms are identified, both for conventional B = 0 and

The relation between the amount ofp-wave in antineutron-proton annihilation into pions at very low momenta (≦ 0.3 GeV/c) and the even or odd character of the produced pion number is underlined. A simple calculation of the magnitude of the effect su

Nucleon-antinucleon at rest presents a variety of channels, where wide mesons often interfere, as shown by the analysis of protonium decay into three pions by the Asterix and Crystal Barrel experiments. A statistical model for emission of the narrow

A phase space model for meson production in antiproton-nucleon annihilation in flight is proposed and shown to be very successful. The distortion of phase space when annihilation occurs inside a nucleus is studied, assuming that the meson masses are

The recent data on double strangeness production after antiproton annihilation on nuclei are analyzed within the conventional picture of the reaction, namely annihilation on a single nucleon, followed by rescattering of the products in the nucleus, a

The excitation of theΔ resonance is observed in proton collisions on C, Nb and Pb targets at 0.8 and 1.6 GeV incident energies. The mass E0 and widthΓ of the resonance are determined from the invariant mass spectra of correlated (p, π±)-pairs in

Recent experimental data concerning antiproton annihilation at rest on light nuclei ( 2 H, 3 He, 4 He, 14 N and 20 Ne) are analyzed in order to disentangle the effect of the rescattering from the genuine B = 1 annihilation. Particular attention is pa

The hypernucleus formation after antiproton annihilation on atomic nuclei is studied in the frame of an intranuclear cascade picture. The basic mechanism is the formation of an antikaon in the annihilation itself, followed by the production and the c

The measurement of fast protons and neutrons emitted after antiproton annihilation at rest on238U and63Cu reveals a large neutron/proton ratioR. Its value for63Cu is larger than expected from the conventional model of intranuclear pion rescattering.
