Supersymmetric Lepton Flavor Violation at the NLC
Supersymmetric theories generally have new flavor violation sources in the
squark and slepton mass matrices. If significant lepton flavor violation
exists, selectron and smuon should be nearly degenerate. This leads to the
phenomenon of slepton oscillations, which is analogous to neutrino
oscillations, if sleptons are produced at the Next Linear Collider. The direct
slepton production at the Next Linear Collider provides a much more powerful
probe of lepton flavor violation than the current bounds from rare processes,
such as .Comment: 5 pages, LaTeX, 1 figure, Talk presented at the 1st Symposium on

Precision Supersymmetry Measurements at the e^-e^- Collider
Measurements of supersymmetric particle couplings provide important
verification of supersymmetry. If some of the superpartners are at the
multi-TeV scale, they will escape direct detection at planned future colliders.
However, such particles induce nondecoupling corrections in processes involving
the accessible superparticles through violations of the supersymmetric
equivalence between gauge boson and gaugino couplings. These violations are
analogous to the oblique corrections in the electroweak sector of the standard
model, and can be parametrized in terms of super-oblique parameters. The collision mode of a future linear collider is shown to be an excellent
environment for such high precision measurements of these SUSY parameters,
which will provide an important probe of superparticles beyond reachable
energies.Comment: 12 pages, 4 figures, LaTeX, Talk presented at the 2nd International
