Bi-Maximal Neutrino Mixing in SO(10)_{GUT}

Abstract

We find a grand unified SO(10) model which accommodates the bi-maximal neutrino mixing for vacuum-oscillation solutions to the atmospheric and the solar neutrino problems. This model maintains the original SO(10) mass relation between neutrino and up-type quark masses, $m_{{\nu }_2}/m_{{\nu }_3}\sim (m_c/m_t{)}^2$.
