The Proceedings discusses the present state of the art in detector development and design for high energy particle physics and astrophysics, both for the next generation experiments and for apparatus upgrade.

This book makes an assessment of the state of the art regarding a new technology, GaAs, which will eventually become vital to construction of the apparatus for high energy physics at future accelerators.

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.
