Muon g-2 and New Physics
Abstract
Description
Here we invoke the current and future perspective on muon $g-2$ measurement when asking what the muon $g-2$ could tell about the underlying structure concerning with the hierarchy problem. Here we take up two such models, the presence of which turns out to alter the standard model prediction for muon $g-2$ significantly: one is TeV scale gravity scenario, the other supersymmetric model, in the latter case of which the precision measurement up to $Z$ boson mass is taken into account as an explicit constraint.
