ELECTRON-ELECTRON SCATTERING AT TeV ENERGIES: AN INTEGRAL PART OF ANY LINEAR COLLIDER PROGRAM

Abstract

We argue that at energies well beyond LEP II, no linear collider program makes sense unless it includes electron-electron scattering. Both their quantum numbers and the high degree of polarization achievable in both incoming beams set this initial state apart from the traditional annihilation channel; these features make experimentation at the edge of, and beyond, the Standard Model particularly promising, and complement the physics program of e+e− interactions in a unique and novel fashion.
