The Physics Capabilities of μ + μ − Colliders ∗

Cern-th/97-367 Physics at Future Colliders

After a brief review of the Big Issues in particle physics, we discuss the contributions to resolving that could be made by various planned and proposed future colliders. These include future runs of LEP and the Fermilab Tevatron collider, B factories, RHIC, the LHC, a linear e+e− collider, an e−p collider in the LEP/LHC tunnel, a μ+μ− collider and a future larger hadron collider (FLHC). The Hi...

Higgs Boson Physics in the s - channel at μ + μ − Colliders

Particle Physics Opportunities at μ + μ − Colliders

We discuss the capabilities of future muon col-liders to resolve important particle physics questions. A collider with c.m. energy √ s = 100 to 500 GeV offers the unique opportunity to produce Higgs bosons in the s-channel and thereby measure the Higgs masses, total widths and several partial widths to high precision. At this same machine, tt and W + W − threshold studies would yield superior p...

R-Parity Violation and Sneutrino Resonances at Muon Colliders

In supersymmetric models with R-parity violation, sneutrinos may be produced as s-channel resonances at μ+μ− colliders. We demonstrate that, for R-parity violating couplings as low as 10−4, sneutrino resonances may be observed and may be exploited to yield high precision SUSY parameter measurements. The excellent beam energy resolution of muon colliders may also be used to resolve MeV level spl...

μ colliders interesting ?

We show that current experimental constraints already severely restrict what might be observable at eµ colliders. We identify some cases where it may be possible to probe physics beyond what might be possible at other facilities and make some remarks about physics capability of high energy eµ colliders.
