Abstract

We investigate the lepton flavor violation decays, τ→ μγ, τ→ eγ and μ→ eγ, in the framwork of a squential fourth generation model with a heavy fourth neutrino, ν'. Using the recent experimental bounds, we can obtain the constraints of the 4× 4 leptonic mixing matrix element factors, V_1ν',V_2ν' and V_3ν'. We find that LFV decays can give strigent costraints on the parameter space of the 4th neutrino mass m_ν'.
