The Neutrino Masses in SUSY GUT

Abstract

The neutrino mass problem in $SU(4)\times SU(2{)}_L\times SU(2{)}_R$ SUSY GUT obtained from the compactification of $E_8\times E_8$ heterotic string is analyzed. The estimated values of the neutrino masses and mixing angles can explain the experimental data on solar neutrino flux.
