Experimental search for W/Z pairs and Higgs bosons at very high energy hadron-hadron colliders

Abstract

We study, from an experimental point of view, the main ways to detect standard high mass Higgs bosons (from 300 GeV up to about 1 TeV) when they decay into W- and Z-pairs at the SSC. We also consider the corresponding W- and Z/sup 0/-pair continuum which may itself provide interesting physics, and we pay some attention to the case of an intermediate mass charged Higgs decaying into tau..nu../sub tau/ (m/sub H+-/ = 300 GeV). We first explain why and how high energy pp colliders may search for Higgs' and we compare their possible performances to those of the e/sup +/e/sup -/ and ep colliders at all possible mass scale (from few tens of GeV's up to 1 TeV). We then estimate the rates of the signals and the main backgrounds. We define the main characteristics of these events as reproduced by M.C. generators (especially implemented with these processes) and simulated through an idealized 4..pi.. fine-grained calorimeter. A trigger strategy for W- and Z-pairs is derived from this study. 26 refs., 28 figs
