We consider, in the electroweak standard model context, several left-right asymmetries in μe elastic scattering at fixed target and collider experiments. For the former case, we show that the muon mass effects are important in a wide energy range. We also show that these asymmetries are sensitive to the electroweak mixing angle θW. The effect of an extra Z′ neutral vector boson appearing in a 331 model is also considered. The capabilities of these asymmetries in the search of this extra Z′ are addressed.
