1. Introduction. Supersymmetric theories have been of interest recently, because they may provide a solution to the gauge hierarchy problem \[1\ ] by explaining why the scale of electroweak interactions (300 GeV) is many orders of magnitude less than the grand unification scale (or the Planck mass). In supersymmetric theories, for each presently known fermion there exists a scalar partner. If supersymmetry is relevant to the solution of the hierarchy problem, then the masses of these scalars cannot be much larger than the weak interaction scale of 300 GeV. In fact, they could even be lighter. Thus, one way to test supersymmetric models experimentally is to search for new scalar particles. However, it has been a major disappointment that absolutely no experimental evidence for or against supersymmetry has been found \[2\]T. herefore, it is essential to seek further means for determining whether supersymmetry is relevant and which classes of models are indicated.

N2 - One major problem for supersymmetry has been the lack of any experimental motivation. Although scalar neutrinos are usually predicted to be among the lighter new particles, their presence has been expected to be hidden because of their decay into unobserved neutrals. We calculate the decays of the scalar neutrino and show that there may be a substantial rate into charged particles. These decay modes lead to very distinctive signatures for supersymmetry in e+e- physics and in W±, Z0 decays.
