Higgs-flavon mixing and h → μτ

Atlas and cms have reported an excess in the flavor violating decay of the higgs boson, h → μτ . we show that this result can be accommodated through a mixing of the higgs with a flavon, the field responsible for generating the yukawa matrices in the lepton sector. we employ a version of the froggatt-nielsen mechanism at the electroweak scale, with only the leptons and the flavon transforming non-trivially under the corresponding symmetry group. non-observation of charged lepton flavor violation (lfv) in other processes imposes important constraints on the model, which we find to be satisfied in substantial regions of parameter space.
