Title: Conference Salam/Musset

Abstract

Le DG L.Van Hove introduit le Prof. A.Salam né en 1926 dans l'ouest du Pakistan, un des gagnants du prix nobel de physique de cette année. Célébration de ses contributions théoriques mondialement connues. Après chaque discours, un petit historique est présenté par Paul Musset. Mention honorable aussi pour l'expérience Gargamelle et ses collaborateurs.

  • The spontaneous breaking of grandunified groups like SO(10) or SU(8) x SU(8) can lead to an extra U(1) group beyond Weinberg-Salam (W-S) SU(2) x U(1). Neutral current data are now shown to depend on two more parameters. The data are examined and limits are put on the mass of the extra Z boson. Need for more experiments on parity violation effects in atoms is stressed. 2 figures, 1 table.
  • There were 5 events of the reaction ..nu../sub ..mu../ + e/sup -/ ..-->.. ..nu../sub ..mu../ + e/sup -/ in a sample of approximately 50,000 charged current neutrino interactions in a heavy neon-hydrogen mixture in the 15 foot bubble chamber at Fermilab. This result is in rough agreement with the prediction of the Weinberg-Salam model with the currently favored value of the mixing angle, sin/sup 2/ theta approximately 1/4.
  • This report discusses the concept of baryon and lepton number violation in the Weinberg-Salam theory. The topics discussed are: periodic vacua in quantum mechanics; tunnelling at finite temperature and classical thermal activation; calculation of the rate; an O(3) nonlinear sigma model; and the transition rate in the O(3) model.

  • The spontaneous breaking of grandunified groups like SO(10) or SU(8) x SU(8) can lead to an extra U(1) group beyond Weinberg-Salam (W-S) SU(2) x U(1). Neutral current data is now shown to depend on two more parameters. We examine the data and put limits on the mass of the extra Z boson. Need for more experiments on parity violation effects in atoms is stressed.
  • The following topics are discussed: F/sub 4/ lattices and their importance for the simulation of heavy Higgs systems, a soft-pion-finite size theorem and the measurements of f/sub pi/ and Adler's Overrelaxation Algorithm and critical slowing down. Several general comments are also given. 10 refs.
