The Standard Model does not provide a very good fit to the most recent precision electroweak data from LEP, due primarily to the observed branching ratios for Z decay to bb̄ and cc̄. The possibility that an extension of the Standard Model with low-energy supersymmetry can improve the agreement between data and theory is considered. Invited Talk at the 1995 International Europhysics Conference on ...
