Signals for Neutralino Box Effects at LEP2
Abstract
We have computed the contribution to the observables of the final two fermion channel at LEP2, at the limiting energy

. We find a potentially visible effect only for the muon channel, in the cross section and, to a lesser extent, in the forward-backward asymmetry. Analogous effects coming from the chargino box are also briefly discussed.
