Leptoquark Production in Scattering
We consider the production of scalar and vector leptoquarks in
collisions. Although this reaction is not competitive with {\em e.g.}
scattering for discovering these heavy states, it is the main
process susceptible of differentiating two important classes of leptoquarks.Comment: 9 pages, talk presented at the Santa Cruz e-e- Workshop, UCSC, 4-5

Selectron Searches in Scattering
We review the pair-production and decay of selectrons in collisions
and show how the standard model backgrounds can be virtually eliminated with
polarized beams. The exceedingly simple analysis involved and the large sample
of background-free supersymmetric events make this linear collider operating
mode ideal for discovering selectrons and measuring the mass of the lightest
neutralino.Comment: 6 pages, talk presented at the Santa Cruz e-e- Workshop, UCSC, 4-5

Bileptons: Present Limits and Future Prospects
We define bileptons to be bosons coupling to a pair of leptons and construct
the most general dimension four lagrangian involving scalar and vector
bileptons. We concentrate on fields with lepton number 2, and derive model
independent bounds on their masses and couplings from low-energy data. In
addition, we study their signals in high energy experiments and forecast the
discovery potential of future colliders.Comment: 60 page
Physics with Like-Sign Muon Beams
We point out that both the specific lepton number content and the high
energies potentially attainable with muon-muon colliders make it advisable to
consider the technical feasibility of including an option of like-sign incoming
beams in the studies towards a proposal to build a muon-muon collider with
center-of-mass energies in the TeV region. This capability will add some unique
physics capabilities to the project. Special attention will have to be paid to
polarization retention for the muons.Comment: 13 pages, uuencoded postscript file, also available from

Model-Independent Limits from Electron-Electron Collisions
Model independent constraints on the mass of an extra neutral gauge boson and
its couplings to charged leptons are given for the option of a future
linear collider. Analytic exclusion limits are derived in the Born
approximation. The results are compared with those of the mode. The
influence of radiative corrections is discussed.Comment: 7 pages, LaTeX, 4 Figures, uuencoded Postscriptfile, MPI-Ph/94-23,
