Summary of the Supersymmetry Working Group

We summarize the results obtained by the Supersymmetry Working Group at the 1996 Snowmass Workshop. I. INTRODUCTION Supersymmetry (SUSY) is a novel symmetry which relates the properties of bosons and fermions. It implies that the elementary particles come in pairs, with the same masses and internal quantum numbers, but with spins differing by one-half unit of angular momentum. Such particles do not exist, so SUSY must be broken (a bosonic electron of mass 0.511 MeV could not have escaped detection). Interest in SUSY phenomenology stems from the fact that in a supersymmetric theory, the masses of elementary scalar particles remain stable under radiative corrections -- even if supersymmetry is softly broken. For the case of the standard model (SM), this suggests that the scale of SUSY breaking should be comparable to the weak scale, ¸ 250 GeV. In this case, the unobserved SUSY partners must have masses smaller than ¸ 1 TeV, and they should be copiously produced at the next generation of..
