We have examined how a Standard Model or Supersymmetric Higgs boson h might be detected at possible hadron colliders. The channels W(to ell nu)h(to b b~), Z(to ell ell~)h(to b b~) and W/Z(to jets)h(to tau+ tau-) are most useful. The results…
We discuss the connection between the understanding of TeV scale physics to be found at the LHC and a high energy e+e- linear collider, using Higgs physics, low energy supersymmetry, and the top quark sector as examples.
The lack of evidence for low energy supersymmetry at the LHC implies a supersymmetry scale in excess a TeV. While this is consistent (and even helpful) with a Higgs boson mass at $\approx$ 125 GeV, simple supersymmetric models with scalar…
I summarize the abilities of LEP-II, the SSC/LHC hadron colliders, and a future high energy $\epem$ collider (NLC) to detect the Higgs bosons of the Minimal Supersymmetric Model (MSSM). I then review the unique capabilities of a…
