Searching for a W' at the Next-Linear-Collider using Single Photons
We examine the sensitivity of the process e+e- -> nu nubar + gamma to
additional W-like bosons which arise in various models. The process is found to
be sensitive to W' masses up to several TeV.Comment: 8 pages, 8 figures, Latex. To appear in proceedings of "MRST '99:

Discovery and Identification of W' Bosons at e+e- Colliders
We report on studies of the sensitivity to extra gauge bosons of the
reactions e^+ e^- -> nu nubar gamma and e gamma -> nu q + X to extract
discovery limits for W' 's. The discovery potential for a W' is, for some
models, comparable to that of the LHC. These processes may be also useful for
determining W' and Z' couplings to fermions which would complement measurements
made at the Large Hadron Collider.Comment: 3 pages, 2 postscript figures, Presented at the DPF2000 Conference,

Constraints on Extra Gauge Bosons in e gamma Collisions
We investigate the sensitivity of e- gamma ---> nu_e nu_mu(bar) mu- to extra
charged gauge bosons. The sensitivity is much below that of e-e+ ---> nu
nu(bar) gamma. We conclude that e- gamma ---> d u(bar) nu_e and e- gamma ---> f
f(bar) e- are also inferior to e+e- collisions in setting bounds on extra
charged and neutral gauge bosons and on four fermion contact interactions.Comment: 6 pages Latex, 5 figures included by epsf, uses e-e-ijmpa.sty and
