Superpartners and Future Colliders

This talk focuses on two aspects of the search for super symmetry. First I argue that if the breaking of the electroweak symmetry is indeed explained by supersymmetry, then it is very likely that superpartners will be produced at Fermilab. Second, once superpartners are found we will move to the next stage where we need to learn the implications of how supersymmetry is realized for the underlying theory, e.g. string theory. The connection between data and the underlying theory is via the supersymmetry soft-breaking Lagrangian. Measuring the Lagrangian requires a lepton collider with a polarized beam, above the threshold for producing some of the superpartners.
