[en] As an instructive exercise in elementary quantum physics the relationship between the sizes of circular particle accelerators and the fundamental constants of nature is explored. (author)

[en] The two broad aims of particle physics, to study the ultimate constituents of matter: to find the smallest building blocks out of which we and the rest of the universe are made, and to study the nature of the forces through which these particles interact are discussed. In the early 1930s scientists had a relatively simple picture of elementary particles. Nuclei consisted of clusters of positively charged protons and uncharged neutrons having dimensions of around 10^-15 m. The nucleus was surrounded by a cloud of orbiting electrons, equal in number to the protons, to make an atom whose dimensions were around 10^-10 m. In addition the photon, the packet or quantum of light, was recognised as having particle-like properties. The idea that there might be antiparticles came not from experiment but from theoretical reasoning. The reasoning and the experiments which confirmed the theories put forward over the next decades are recounted. These culminated in the experiments at CERN in 1982 and 1983 to discover the W and Z particles. (author)

[en] The properties and interactions of antiprotons are considered and the possibility of cooling antiproton beams, storing them and allowing them to collide at very high energies with protons is discussed. The question of matter-antimatter cosmology is examined. (U.K.)

[en] This book examines recent advances in our understanding of particle physics and the forces of nature, presents invited papers on various subjects. Topics include the present status of quarks and leptons, new physics from the CERN collider, and options for machines and experiments in the future

[en] Differential and total cross sections for elastic anti pp scattering are measured. The energy range studied varied from 0.69 to 2.43 GeV/c

[en] The highest energy particle accelerators in operation and under construction are described briefly, together with a selection of detectors. Extrapolations of existing techniques both for accelerators and for detectors appear to be adequate for the next upward step in energy, but beyond this new techniques will probably have to be developed. Some predictions are given. (author)

[en] Events of the type anti pp → K^-K⁺, π^-π⁺ were studied at 0.79 to 2.43 GeV/c. Differential cross sections and Legendre coefficient ratios are shown. Resonances found as a result of model fitting showing spin--parity assignment versus mass squared are also shown

[en] The great majority of experiments in particle physics use beams of particles from accelerators. Individual interactions of these with other particles are observed by detector systems. Fixed target and colliding beam experiments are contrasted, and non-accelerator experiments mentioned briefly. An account is given of the principles of the various detectors. These include scintillation and Cerenkov counters and the various tracking devices such as bubble chambers, proportional and drift chambers. Calorimeters have emerged recently as important detectors at the highest energies. Electronic logic modules are mentioned and the main steps in data acquisition and analysis are described. Finally an example is given of a large detector system. (author)

[en] The modern study of particle physics allows us to recreate some of the conditions of the early universe during the Big Bang. To study the smallest objects in nature requires the largest equipment, such as the accelerators at CERN, the European Laboratory for Particle Physics. The experiments have shown that all matter is composed of two types of building block, and the number of distinct forces by which these interact has been reduced from four to three. (author)
