Standard Model Higgs Boson Studies for Supercolliders.
Abstract
Searching for the Higgs boson is imperative to test the spontaneous symmetry breaking mechanism, which is one of the most important concepts in contemporary particle physics. We concentrate on the minimal standard model in this thesis. We have studied in detail Higgs boson production and detection in future high energy e ^+e^- and pp collisions. In general, Higgs boson searches can be carried out up to a mass of m_{H} ~sqrt{s}/2 at e ^+e^- colliders. For a pp collider such as the SSC, we should be able to find the Higgs boson if 2M_{Z}<m_ {H}< 1 TeV. For an intermediate mass Higgs boson with M_{Z}<m_ {H}< 2M_{W}, the H searches are problematic in pp collisions due to either severe backgrounds or low rates for cleaner channels. We also studied the H effects on multi-vector boson production. If 2M_{Z}<m_{H}< 0.6 TeV, the H effects should be observable in the channel e^+e^ ---> WWZ at future high luminosity e^+e^- colliders. It is also possible to study the Higgs boson self-interactions by searching for HH pair events in future e^+ e^- collisions.
