Some Aspects of Antiproton–nucleus Physics
نویسنده
چکیده
A brief review of antiproton–nucleus physics is presented. Some topics are related to early LEAR experiments, and others to more recent measurements or proposals. These include: exotic molecules, elastic and inelastic scattering, deep annihilation, strangeness production, neutron–antineutron oscillations, halo nu-clei, antiproton production in nuclear reactions etc.

Subthreshold antiproton production in nucleus-nucleus collisions.
Antiproton production from the secondary process pp~ pp is studied for nucleus-nucleus collisions at energies which are below the threshold for its production from the nucleon-nucleon reaction in the free space. In an expanding fireball model, we determine the p abundance from the fusion of pions and find that for collisions at 2. 1 GeV/nucleon the antiproton to negative pion ratio is = 5.5&10 ...
متن کاملAntiproton Induced Reactions
The various aspects of antiproton physics are shortly reviewed, and its relevance for the possible discovery of new particles and effects is pointed out. Then a survey of the nucleon-antinucleon interactions is given. In the nucleon-antinucleon annihilations, there is a big amount of experimental data that call for theoretical explanation. Importance of specific spin and isospin channels for ou...
متن کامل3 Simulation of antiproton - nucleus interactions in the framework of the UrQMD model
For implementation of the PANDA project (GSI) an antiproton-nucleus event generator is needed. In our paper we propose to apply the Ultra-Relativistic Quantum Molecular Dynamic (UrQMD) approach for this aim. Using the UrQMD model, simulation of ¯ pA-interactions at antiproton energies from 1 GeV to 200 GeV has been performed. We studied the average multiplicities, the multiplicity distributions...

An enhancement of antiprotons produced in p + d reaction in comparison with ones in p + p elementary reaction is investigated. In the neighborhood of subthresh-old energy the enhancement is caused by the difference of available energies for antiproton production. The cross section in p + d reaction, on the other hand, becomes just twice of the one in elementary p + p reaction at the incident en...
