Abstract:

We discussed neutrino masses and mixings in SUSY SO(10) model where quarks and leptons have Yukawa couplings to at least two 10 and one

\bar{126}

Higgs scalars. In this model, the Dirac and the right-handed Majorana mass terms are expressed by linear combinations of quark and charged lepton mass matrices, which then determine the neutrino mass matrix by the see-saw mechanism. We show that there are various solutions to reproduce a large mixing angle for

\nu_\mu-\nu_\tau

and a small mixing angle for

\nu_e-\nu_\mu

, as well as the hierarchical mass spectrum of neutrinos.

quark: mass generation
lepton: mass generation
quark: mixing angle
lepton: mixing angle
grand unified theory: SO(10)
supersymmetry
