A simple model of spacetime foam, made by N wormholes in a semiclassical approximation, is taken under examination. We show that the qualitative behaviour of the fluctuation of the metric conjectured by Wheeler is here reproduced.

Searches for supersymmetry at LEP allowing for R p are reviewed. The results are compared with the R p conserving scenario. Searches for supersymmetry at LEP allowing for Rp are reviewed. The results are compared with the Rp conserving scenario.

We consider simple-pole descriptions of soft elastic scattering for pp, p̄p, πp and Kp. We work at t and s small enough for rescatterings to be neglected, and allow for the presence of a hard pomeron. After building and discussing an exhaustive dataset, we show that simple poles provide an excellent description of the data in the region −0.5 GeV2 ≤ t ≤ −0.1 GeV2, 6 GeV≤ √s ≤ 63 GeV. We show that...
