    Any consideration of future physics facilities must be made in the context of the Tevatron and the LHC. I discuss some examples of physics results which could emerge from these machines and the resulting questions which would remain for a high energy e+e−e^+e^- collider. Particular attention is paid to the electroweak symmetry breaking sector. If a light Higgs boson exists, it will be observed at the LHC and the role of any later accelerator will be to map out the Higg's boson mass and couplings and then determine the space of possible models. If there is no light Higgs boson, then some effects of a strongly interacting electroweak symmetry breaking sector will be observed at the LHC and I discuss the role of a high energy linear collider in exploring this scenario.Comment: Invited talk given at Workshop on Studies on Colliders and Collider Physics at the Highest Energies: Muon Colliders at 10 TeV to 100 TeV, Montauk, New York, Sept. 27- Oct. 1, 199

    DPF `96: The triumph of the Standard Model

    Get PDF
    I summarize some of the highlights of the 1996 DPF meeting, paying particular attention to new measurements of the WW, ZZ, and top quark masses. Precision electroweak measurements from LEP are discussed with emphasis on recent measurements of RbR_b and values of the coupling constants α(MZ2)\alpha(M_Z^2) and αs(MZ2)\alpha_s(M_Z^2) are presented. Taken as a whole, the data are in spectacular agreement with the predictions of the Standard Model.Comment: Summary talk given at the 1996 DPF meeting, Minneapolis, Minn., Aug. 10-15, 1996; uses sprocl.sty, 8 p

    We discuss recent results from global electroweak fits and from the Tevatron and review the motivation for physics at the TeV energy scale.Comment: To appear in the Proceedings of the 15th Topical Conference on Hadron Collider Physics (HCP 2004), 14-18 July, 2004, Michigan State University, East Lansing, Michiga

    Precision Measurements at a Muon Collider

    We discuss the potential for making precision measurements of MWM_W and MTM_T at a muon collider and the motivations for each measurement. A comparison is made with the precision measurements expected at other facilities. The measurement of the top quark decay width is also discussed.Comment: Latex file using mu95.sty (appended at end) and epsf, 4 gzipped figures.

    We discuss associated production of a Higgs boson with a pair of ttˉt {\bar t} quarks at a future high energy e+e−e^+e^- collider. The process e+e−→ttˉhe^+e^-\to t {\bar t}h is particularly sensitive to the presence of new physics and we consider the MSSM and models with extra dimensions at the TeVTeV scale as examples.Comment: Talk given at the 5th International Collider Workshop (LCWS 2000), Fermilab, Batavia, Il, Oct 24-28, 200
