Sažetak
We study charged lepton flavor violation in low- scale seesaw models of constraint minimal supersymmetric standard model (CMSSM), which realize large neutrino Yukawa couplings thanks to approximate flavor symmetries. There are two dominant sources of lepton flavor violation in such models. The first source originates from the usual soft supersymmetry-breaking (SB) sector, whilst the second one is entirely supersymmetric and comes from the supersymmetric neutrino Yukawa sector. Within the mSUGRA framework, we consider both sources of lepton flavor violation, soft and supersymmetric, and calculate a number of possible lepton-flavor-violating transitions, among which are the photonic decays of muons, μ → e, its neutrinoless 3-body decay, μ → eee, and the coherent μ → e conversion in nuclei. Detailed analysis of form-factor contributions and soft and supersymmetric contributions has been performed.
