This volume discusses the most recent results on multiparticle production. These include the differences between quark and gluon jets from LEP at CERN, the search for the disoriented chiral condensate at Fermilab, the existence (or not) of the quark-gluon plasma and the large rapidity gaps in Hera physics. In many different experimental situations, the subject of multiparticle dynamics remains alive.Main speakers: J Antos, B J May, J D Bjorken, P Sondereger, I Tserruya, R C Hwa, R Ugoccioni, A Giovannini, C Grupen, A de Angelis, G Thompson, J Kwiecinski, B Andersson.

These proceedings consist of plenary rapporteur talks covering topics of major interest to the high energy physics community and parallel sessions papers which describe recent research results and future plans.

The 4th San Miniato Topical Seminar on “The Standard Model and Just Beyond” was a continuation of the meetings held in 1985, 1987 and 1991, and covered essentially similar topics. The program focused on reviews of the present experimental progress in precise electroweak and QCD tests, heavy flavour physics (particularly mixing) and the search for new particles. The emphasis was on the most recent results coming from the large statistics data samples collected at LEP, other e+e- machines, hadron colliders and fixed target experiments. The present status of the theory was reviewed and one session was dedicated to the discussion of future plans and physics issues.
