Deviations from tribimaximal and golden ratio mixings under radiative corrections of neutrino masses and mixings

Abstract

The impact of renormalization group equations on neutrino masses and mixings at high-energy scales in the Minimal Supersymmetric Standard Model is studied using two different mixing patterns such as Tribimaximal (TBM) mixing and Golden Ratio (GR) mixing in consistent with cosmological bound of the sum of three neutrino masses, [Formula: see text]. Magnifications of neutrino masses and mixing angles at low-energy scales are obtained by giving proper input masses, and mixing angles from the TBM mixing matrix and GR mixing matrix at high-energy scales. High-energy scales, [Formula: see text] such as [Formula: see text], [Formula: see text], [Formula: see text] GeV are employed in the analysis. The large solar ([Formula: see text]) and atmospheric ([Formula: see text]) neutrino mixing angles with zero reactor angle ([Formula: see text]) from both TBM mixing matrix and GR mixing matrix at high scale, can magnify the reactor angle ([Formula: see text]) at low-energy scale in 3[Formula: see text] confidence level. Both cases of normal hierarchy and inverted hierarchy are addressed here. In a normal hierarchical case, it is found that [Formula: see text] and that in an inverted hierarchical case is [Formula: see text] in both mixing patterns. Possibility of [Formula: see text] or [Formula: see text] is observed at low scale. The analysis shows the validity of the two mixing patterns at a high-energy scale.
