A novel technique for longitudinal segmentation of shashlik calorimeters has been tested in the CERN West Area beam facility. A 25 tower very fine samplings e.m. calorimeter has been built with vacuum photodiodes inserted in the first 8 radiation lengths to sample the initial development of the shower. Results concerning energy resolution, impact point reconstruction and e/π separation are repo...

We discuss the influence of a zero-temperature environment on a coherent quantum system. First, we calculate the reduced density operator of the system in the framework of the well-known, exactly solvable model of an oscillator coupled to a bath of harmonic oscillators. Then, we propose the sketch of an Aharonov–Bohm-like interferometer showing, through interference measurements, the decrease o...

We review the status of searches for Supersymmetry at the Tevatron Collider. After discussing the theoretical aspects relevant to the production and decay of supersymmetric particles at the Tevatron, we present the current results for Runs Ia and Ib as of the summer of 1997.

We study the β–function of the N = 2 σ–model coupled to N = 2 induced supergravity. We compute corrections to first order in the semiclassical limit, c → −∞, beyond one–loop in the matter fields. As compared to the corresponding bosonic, metric σ– model calculation, we find new types of contributions arising from the dilaton coupling automatically accounted for, once the Kähler potential is cou...
