Finding the missing pieces of the standard model

The standard model is discussed in general and the predicted, but as yet unobserved, Higgs boson and top quark described. Detection of a top quark at electron positron colliders and hadron colliders is considered for top-quark mass of under 80 GeV. The detection of the Higgs boson is considered at the Z peak in electron positron annihilation for Higgs-boson masses equal to or less than 60 GeV, as well as in the continuum 100-200 GeV (intermediate mass range). For this range of the Higgs-boson mass, consideration is also given to its detection at the Superconducting Supercollider through the tau-lepton decay mode. A dispersive approach is considered for Higgs boson with large mass, equal to or greater than 500 GeV, in order to estimate nonperturbative self interaction effects.
