Abstract

The discrete subgroup Delta(27) of SU(3) has the interesting multiplication rule 3 X 3 = bar{3} + bar{3} + bar{3}, which is used to obtain near tribimaximal neutrino mixing. Using present neutrino oscillation data as input, this model predicts that the effective mass m_{ee} measured in neutrinoless double beta decay will be 0.14 eV.
