Abstract

We review the search for the standard Higgs boson, the Higgs bosons of the supersymmetric standard model, and Higgs bosons from a variety of other models at present and future colliders. 1 Introduction 1.1 Standard Higgs model The evidence is overwhelming that the electroweak interaction is described by an SU(2)L\Theta U(1)Y gauge theory, spontaneously broken to electromagnetism, U(1)EM. The symmetry breaking provides the masses of the W and Z bosons, as well as the masses of the fermions and the Cabibbo-Kobayashi-Maskawa (CKM) mixing between the quarks (including CP violation). Electroweak symmetry breaking is therefore associated with most of the aspects of the electroweak interaction which remain beyond our grasp. Uncovering the electroweak-symmetry-breaking mechanism is essential for progress in our quest to describe nature at a deeper level. Little is known about the mechanism which breaks the electroweak symmetry. The fact that the relation mW = mZ cos `W is nearly satisfied suggests that the symmetry-breaking sector possesses a global SU(2) symmetry, often called a "custodial " symmetry [1-3]. Precision electroweak experiments [4,5] and flavorchanging-neutral-current processes [6] indirectly constrain the electroweak-symmetrybreaking sector.
