A brief introduction to the theory and phenomenology of soft interactions is given, focusing on total and elastic cross sections and multiparticle production.

We comment on the changes in the constrained model studied earlier when constituent massless vector fields are introduced. The new model acts like a gauge-Higgs-Yukawa system, although its origin is different. PACS 11.10.-z, 12.60.Rc

We consider the extension of the standard model with an arbitrary number of U (1) gauge fields coupled to baryon-minus-lepton number and/or hypercharge. Under the assumption that A b fb from the LEP1 experiment is an unlucky fluctuation, we find moderate evidence for the presence of such fields in the precision electroweak data. A relatively large range of the Higgs boson mass is allowed. We di...
