Abstract
In the context of \[SU(3)_C \times SU(2)_L \times U(1)_Y \times U(1)_\chi \], where \[U(1)_\chi \] comes from \[SO(10) \rightarrow SU(5) \times U(1)_\chi \], supplemented by the non-Abelian discrete \[\Delta (27)\] symmetry for three lepton families, Dirac neutrino masses and their mixing are radiatively generated through dark matter. The gauge \[U(1)_\chi \] symmetry is broken spontaneously. The discrete \[\Delta (27)\] symmetry is broken softly and spontaneously. Together, they result in two residual symmetries, a global \[U(1)_L\] lepton number and a dark symmetry, which may be \[Z_2\], \[Z_3\], or \[U(1)_D\] depending on what scalar breaks \[U(1)_\chi \]. Cobimaximal neutrino mixing, i.e. \[\theta _{13} \ne 0\], \[\theta _{23} = \pi /4\], and \[\delta _{CP} = \pm \pi /2\], may also be obtained.
