If supersymmetry is discovered at future colliders, what can we learn? While our appreciation of the variety of possible supersymmetric models has grown tremendously in recent years, most attempts to answer this question have been in the context of some simple and highly restrictive framework, such as minimal supergravity. In this talk I describe new probes of phenomena that are generic in models...
In supersymmetric theories the charged sleptons of different generations may oscillate amongst themselves while they decay. In the case of three generation oscillations, superpartner production at the LHC and NLC may lead to an observable CP-violating signal N(e + μ - ) - N(μ + e - ). This signal is proportional to a CP-violating invariant of the slepton mass matrix,...
Supersymmetric models are typically taken to have μ parameter and all soft supersymmetry breaking parameters at or near the weak scale. We point out that a small window of allowed values exists in which μ and the electroweak gaugino masses are in the few GeV range. Such models naturally solve the supersymmetry CP problem, can reduce the discrepancy in R b , and suppress proton decay. In...
