Lepton number violation in a little Higgs model

Abstract

In this note we examine the constraints imposed by muon anomalous magnetic moment ($(g\ensuremath{-}2{)}_{\ensuremath{\mu}}$) and ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}{e}^{\ensuremath{-}}$ on lepton number violating (LNV) couplings of the triplet Higgs in Little Higgs (LH) model.
