Proceedings of the Workshop on Program Options in Intermediate-Energy Physics. Keynote address: New directions in elementary particle physics - pantip from very low to very high energies

摘要

The recent development of cooling techniques offers the possibility to obtain intense sources of antiprotons, stacking them as they are produced at a multi-GeV accelerator. The wide array of applications presently considered, ranging from reactions at extremely low energy in the case of p anti p atoms to reactions at hundreds of GeV in the case of head-on collisions between protons and antiprotons accelerated at the same time in a super synchrotron, is reviewed. Special emphasis is put on the present CERN program, which will reach the data-taking stage in 1981. The study of p anti p interactions is meant as an illustration of how new possibilities open new directions in elementary particle physics, whether reaching energies hitherto much beyond accelerator possibilities or developing new lower-energy beams improved tremendously over those presently available. 14 figures, 1 table.
