Summary Report for the $e^{-}{e}^{-}$ session in LCWS 2004

Abstract

In this talk, I summarize the activities in the $e^{-}{e}^{-}$ session. The consensus is that if the next generation $e^{+}{e}^{-}$ linear collider wants to include an $e^{-}{e}^{-}$ option, the planning has to include it as early as possible. By doing so the extra cost would be only a small fraction of the total, and of course the physics potential would be very rewarding.
