The 1994 Cargese Summer Institute on Frontiers in Partide Physics was organized by the Universite Pierre et Marie Curie, Paris (M. Levy), the Ecole Normale Superieure, Paris (J. Iliopoulos), the Katholieke Universiteit Leuven (R. Gastmans), and the Uni- versite Catholique de Louvain (J. -M. Gerard), which, since 1975, have joined their efforts and worked in common. It was the eleventh Summer Institute on High Energy Physics organized jointly at Cargese by three of these universities. Severa! new frontiers in partide physics were thoroughly discussed at this school. the new euergy range in deep-iuelastic electron-proton scattering is beiug In particular, explored by HERA (DESY, Hamburg), and Professor A. De Roeck described the first results from the H1 and Zeus experiments, while Professors A. H. Mueller aud Z. Kuuszt discussed their relevance from the theoretical point of view. Also, the satellite exper- iments offer new possibilities for exploring the links between astrophysics, cosmology, and partide physics. A critica] a. nalysis of these experiments was performed by Pro- fessor B. Sadoulet, and Professor M.Spiro made the connection with the results from earth-based neutrino experiments. Finally, much attentiou was giveu to the latest re- sults from the TEVATRON (Fermilab, USA), showing further evidence for the loug awaited top quark. Professor A. Tollestrup gave a detailed presentation of these results aud discussed their importance for the Standard Model.

The 1996 Carg~se Summer Institute on Frontiers in Particle Physics was organized by the Universite Pierre et Marie Curie, Paris (M. Levy), the Ecole Nonnale SupCrieure, Paris (J. lliopoulos), the Katholieke Universiteit Leuven (R. Gastmans), and the Universite Catholique de Louvain (J.-M. Gerard), which, since 1975, have joined their efforts and worked in common. It was the twelfth Sunnner Institute on High Energy Physics organized jointly at Carg~se by three of these universities. The Standard Model for fundamental interactions is constructed on two essential ingredients: the gauge symmetry and the mass generation mechanism. Now that the gauge theory aspect has been finnly established, the new challenge for the young researchers in elementary particle physics is the understanding of the origin of the masses. The standard Higgs mechanism is believed to be responsible for generating the masses of ALL fundamental particles. Professor D. Treille discussed the prospects for Higgs boson search and described the experimental determinations of the gauge boson masses. The influence of the top quark mass on electroweak processes has been emphasized by Professor J.L.Rosner, while Professor M. Neubert introduced the heavy-quark effective theory which allows you to get rid of heavy-quark masses. The theoretical determinations of the light- quark masses have been critically analyzed by Professor H. Leutwyler. Professor A. Pich presented the various experimental tests on lepton universality and Professor R.L. MBssbauer reviewed our present knowledge on the neutrino masses.

For more than 25 years, the Standard Model of particle physics has withstood the confrontation with experimental results of increasing precision, but this does not imply that the Standard Model can answer all questions about the ultimate constituents of nature. This book presents a critical examination of the latest experimental results and confronts them with the predictions of the Standard Model. Besides discussions of accelerator results from LEP, HERA and the TEVATRON, attention is paid to the unresolved problems of neutrino oscillations, CP violation, dark matter and cosmology. New theoretical ideas are also analyzed in order to explore possible extensions of the Standard Model. Realistic plans for future accelerators are presented and their physics potential is discussed, paving the way for the next generation of particle physics experiments.

The 1992 Cargese Summer Institute on Quantitative Particle Physics was organized by the Universite Pierre et Marie Curie, Paris (M. Levy and J. -L. Basdevant), CERN (M. Jacob), the Ecole Normale Superieure, Paris (J. Diopoulos), the Katholieke Universiteit te Leuven (R. Gastmans) and the Universite Catholique de Louvain (J-M. Gerard), which, since 1975, have joined their efforts and worked in common. It was the tenth Summer Institute on High Energy Physics organized jointly at Cargese by these three universities. The 1992 School centered on quantitative tests of the Standard Model for electroweak and strong interactions. First, Professor T. D. Lee reviewed the fascinating history of weak interactions. Professor R. Barbieri then discussed the implications of the of LEP presented by Professor Foil. . Professor G. Ecker latest experimental results described in detail the interplay between electroweak and strong interactions at low energy. Professors K. Berkelman and J-M. Gerard stressed the necessity to study the effects of CP-violation in both B-and K-physics. The first results of the HERA machine were presented by Professor G. Wolf, while Professor M.Shochet reviewed heavy flavor physics in hadron collider experiments. Recent non-accelerator experiments in neutrino physics were presented by Professor B. Barish. Finally, Professor M. Turner reviewed Cosmology after COBE. We owe many thanks to all those who have made this Summer Institute possible! Special thanks are due to the Scientific Committee of NATO and its President for a generous grant.
