主　　题：flavor physics neutrino and Lepton mass beyond the standard model 

摘      要：We study a double covering of modular A_(4)flavor *** this end,we construct lepton models for canonical and radiative seesaw *** irreducible doublet representations,heavier Majorana fermion masses are characterized by one free parameter that would differentiate from A_(4)***χsquare numerical analysis,we demonstrate that both scenarios produce some predictions in case of normal hierarchy reproducing neutrino oscillation ***,no solution satisfies the neutrino oscillation data in case of radiative seesaw of inverted hierarchy.
