Supersymmetry and R$_{b}$ in the light of LEP 1.5
We re-examine the possible magnitude of the supersymmetric contribution to R_b\equiv\Gamma(Z^0\to\bar b b)/\Gamma(Z^0\to{\rm all}) in the light of the constraints imposed by the absence of light charginos at LEP~1.5, implementing also other available phenomenological constraints. We find the supersy...
