Physics at a gamma gamma, e gamma and e-e- Option for a Linear Collider
This report presents a review of the studies made in the working group on
gamma gamma and e gamma physics" of the ECFA/DESY workshop on linear collider
physics. It reports on several new physics studies, in particular s-channel
Higgs production. A summary of R&D activities for the interaction region is
presented. The merits of e-e- collisions are briefly recalled.Comment: 10 pages, 20 figures. Proceedings of the ECFA/DESY study on Physics

Determination of the muon Yukawa coupling at high energy e+e- linear colliders
The perspectives for the observation of the rare decay H -> mumu decay and
the determination of the muon Yukawa coupling at a TeV-class and at a multi-TeV
e+e- linear colliders are discussed. The signal for the decay can be obtained
at 0.8 TeV and a first estimate of the coupling derived. A linear collider
operating at 3 TeV, with high luminosity, is able to improve the accuracy on
this couplings to 4% to 11% for 120 GeV < M_H < 150 GeV.Comment: 3 pages, 2 figures, to appear on the proceedings of the Snowmass 2001

Delta G(x) from high p_t hadrons in DIS at a polarised HERA
We investigate the possibility to identify photon-gluon fusion (PGF) events
in polarised deep inelastic ep scattering, assuming the kinematics of the HERA
collider, by a pair of charged high p_t particles. In a Monte Carlo study we
find possible selection criteria and show the expected measurable asymmetries.
We discuss the sensitivity to and compare the result to the one
obtained using di-jets to tag PGF events.Comment: 8 pages, 5 figures, Contributed paper to the Proceedings of the
Workshop on Physics at HERA with Polarized Protons and Electron
