THE ELECTRON–ELECTRON VERSION OF THE LINEAR COLLIDER — A MILLENNIUM UPDATE

Abstract

It has become a natural mandate to the particle physics community to look beyond presently active and approved high-energy accelerators for precision work at the edge of, and beyond, the Standard Model. We stress the mandate for complementary use of both charge modes of the Electron Collider, e+e- and e+e-. Choosing a few illustrative examples, we attempt to set the stage for technical developments needed to define and execute the key experiments using two incoming electron beams.
