Abstract

A multiscalar and nonrenormalizable extension of the standard model (SM) with symmetry which successfully explains the recently observed neutrino oscillation data is proposed. The tiny neutrino masses and their hierarchies are generated via the type-I seesaw mechanism. The model reproduces the recent experiments of neutrino mixing angles and Dirac CP violating phase in which the atmospheric angle and the reactor angle get the best-fit values while the solar angle and Dirac CP violating phase ( ) are in range of the best-fit value for the normal hierarchy (NH). For the inverted hierarchy (IH), gets the best-fit value and together with are in the range, while is in range of the best-fit value. The effective neutrino masses are predicted to be for the NH and for the IH, in good agreement with the most recent experimental data.
