Linear seesaw model with T 7 symmetry for neutrino mass and mixing

Abstract

We propose a low-scale Standard Model extension with symmetry that can successfully explain observed neutrino oscillation results within the range. Small neutrino masses are obtained via the linear seesaw mechanism. Normal and inverted neutrino mass orderings are considered with three lepton mixing angles in their experimentally allowed ranges. The model provides a suitable correlation between the solar and reactor neutrino mixing angles, which is consistent with the pattern. The prediction for the Dirac phase is for both normal and inverted orderings, including its experimentally maximum value, while those for the two Majorana phases are for normal ordering and for inverted ordering. In addition, the predictions for the effective neutrino masses are consistent with the present experimental bounds.
