New Model-Independent Limit on Muon Substructure

Kenneth Lane

Phenomenology Experiment

Abstract

If the discrepancy between the theoretical and newly measured values of the muon's anomalous magnetic moment is ascribed to muon substructure, there results an improved model--independent limit on its energy scale, 1.2 TeV < Lambda_mu < 3.2 TeV at 95% C.L.
