Antiproton-Nucleon and Antiproton-Nucleus Interactions


Book Description

The third 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 10 to 18 June, 1988. 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; the second course in 1987 focused on spectroscopy of light and heavy quarks. This book con tains the Proceedings of the third course, devoted to the experimental and theoretical aspects of the interaction of antinucleons with nucleons and nuclei. The Proceedings contain both the tutorial lectures and contributions presented by participants during the School. The papers are organized in several sections. The first section deals with the theoretical aspects of NN scattering and annihilation, and the underlying QCD. The experimental techniques and results concerning NN scattering are contained in Section II. Section III contains theoretical reviews and contributions on anti proton-nucleus scattering and bound states. Section IV is devoted to the experimental results on the antiproton nucleus systems and their phenomenological analysis. Finally, some possible developments of the antiproton machines are presented.
















Mesons And Nuclei At Intermediate Energies - Proceedings Of The International Conference


Book Description

One of the main goals of intermediate energy nuclear physics, which serves an important role as a bridge between nuclear and particle physics, is to construct the theory of strong interaction phenomena in terms of conventional degrees of freedom (nucleons, deltas and mesons) as well as of quark degrees of freedom.The main topics to be discussed at this conference are the interaction of pions and other mesons with nuclei at intermediate energies and the role of mesonic degrees of freedom in nuclear reactions, including photon, hadron and heavy ion induced reactions. Both theoretical and experimental results will be included.Over the past two decades, the Meson Factories, including LAMPF, TRIUMF, and PSI, have provided us with systematic experimental information on hadron-hadron and hadron-nucleus dynamics. Major accelerators of JINR are also suitable for studying problems in Intermediate Energy Nuclear Physics. At the present time, first experiments have been performed with the proton beams at the Moscow Meson Factory of INR. One of the purposes of this conference is to introduce the intermediate-energy physics community to the possibility of utilizing the facilities of JINR and INR during the next decade.

Physics at LEAR with Low-Energy Cooled Antiprotons


Book Description

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.




Intermediate-Energy Nuclear Physics


Book Description

Intermediate-Energy Nuclear Physics is devoted to discussing the interaction between hadrons with nuclei, which leads to the emission of particles during an intranuclear cascade and subsequent decay of a highly excited residual nucleus. Experimental data and the methods and results of the calculation of probabilities of various processes initiated by intermediate-energy hadrons in nuclei are set forth and discussed. The potential for obtaining information on the structure and properties of nuclei by comparing experimental data with theoretical results is analyzed. New issues, such as analytic methods for the solution of kinetic equations describing the cascade, nuclear absorption of hadrons from bound states of hadronic atoms, interaction of antinucleons with nuclei, multifragmentation of highly excited residual nuclei, and polarization phenomena, are discussed in detail. The book also demonstrates hadron-nucleus interactions that bridge the gap between low-energy and heavy ions physics. It is an interesting reference for nuclear physicists and other researchers interested in the analysis of problems associated with the evolution of the early (hot) universe, neutron stars and supernovas, after-burning of radioactive waste in nuclear energy installations, and electronuclear energy breeding.
