A minimal modular invariant neutrino model
We present a neutrino mass model based on modular symmetry with the fewest
input parameters to date, which successfully accounts for the 12 lepton masses
and mixing parameters through 6 real free parameters including the modulus. The
neutrino masses are predicted to be normal ordering, the atmospheric angle
is quite close to maximal value and the Dirac CP phase
is about . We also study the soft supersymmetry breaking
terms due to the modulus -term in this minimal model, which are constrained
to be the non-holomorphic modular forms. The radiative lepton flavor violation
process is discussed.Comment: 24 pages, 4 figure
