Left-right asymmetries in polarized e-μ scattering
Abstract
We consider, in the electroweak standard model context, several left-right asymmetries in μ e 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.
