Few-body problems
No full textThis volume consists of two review articles. E Hadjimichael's contribution, 'The Nuclear Three-Body Systems', concentrates on recent experimental and theoretical progress achieved in the field. Together with a pedagogical survey of the theoretical framework extensive discussion on the 3N system in the continuum and reactions of electromagnetic probes with 3N systems are provided. 'Four-Nucleon Transfer Reactions' by W Oelert reviews many aspects of a-particle transfer studies. A careful and balanced presentation of both theory and experiment is given. Reasonable agreement between the two is o
Hadronic threshold reactions
No full textFirst investigations on meson production at threshold in the strong interaction began in the fifties when sufficient energies of accelerated protons were available. Early experiments performed with bubble chambers revealed already typical ingredients of threshold studies, which were superseded by more complete meson production investigations at the nucleon beam facilities TRIUMF, LAMPF, PSI, LEAR and SATURNE. Currently, at the cooler rings IUCF, CELSIUS and COSY the field is entering a new domain of precision and further progress. The analysis of this new data in the short-range limit permits a more fundamental consideration and a quantitative comparison of the production processes for different mesons in the few-body final states. The interpretation of the data takes advantage of the fact that production reactions close to threshold are characterized by only a few degrees of freedom between a well-defined combination of initial and exit channels. Deviations from predictions of phase-space-controlled one-meson exchange models are indications of new physics. Precision data on differential cross-sections, isospin and spin observables --partly but by no means adequately available-- are presently turning up

ELENA: An Upgrade to the Antiprotondecelerator at CERN
No full textCERN has a long tradition of pursuing fundamental physics on a variety of energy scales. For anti-protons CERN famously produced the high-energy SPS beam but also the world's only and unique sources of low-energy anti-protons - first the Low Energy Anti-proton Ring (LEAR) and thereafter the Anti-proton Decelerator (AD).The scientific demand for low-energy anti-protons at the AD continues to grow. More rapid progress and much higher measurement precision might be possible by upgrading the AD to increase and optimize the number of cold anti-protons that can be trapped and accumulated. To achieve this the construction of an Extra Low ENergy Antiproton (ELENA) ring is proposed which involves both the addition of a small storage ring and electrostatic beam lines to the experiments. The design parameters have been carefully studied and agreed upon over several years. At least during the next decade there is no alternative low-energy anti-proton source for physics to be done now
