Role of lepton flavor violating (LFV) muon decay in Seesaw model and LSND
Abstract
The aim of the work is to study LFV in a newly proposed Seesaw model of neutrino mass and to see whether it could explain LSND excess. The motivation of this Seesaw model was that there was no new physics beyond the TeV scale. By studying μ 3e in this model, it is shown that the upper bound on the branching ratio requires Higgs mass mh of a new scalar doublet with lepton number L=-1 needed in the model has to be about 9 TeV. The predicted branching ratio for μ ell is too small to explain the LSND. PACS: 11.30.Hv, 14.60.Pq
