Neutrino mixing angles in sequential dominance to NLO and NNLO

Neutrino mixing angles in sequential dominance to NLO and NNLO
Neutrino mixing angles in sequential dominance to NLO and NNLO
Neutrinos with hierarchical masses and two large mixing angles may naturally
originate from sequential dominance (SD). Within this framework we present analytic
expressions for the neutrino mixing angles including the next-to-leading order (NLO)
and next-to-next-to-leading order (NNLO) corrections arising from the second lightest and
lightest neutrino masses. The analytic results for neutrino mixing angles in SD presented
here, including the NLO and NNLO corrections, are applicable to a wide class of models
and may provide useful insights when confronting the models with data from high precision
neutrino experiments. We also point out that for special cases of SD corresponding to
form dominance (FD) the NLO and NNLO corrections both vanish. For example we study
tri-bimaximal (TB) mixing via constrained sequential dominance (CSD) which involves
only a NNLO correction and tri-bimaximal-reactor (TBR) mixing via partially constrained
sequential dominance (PCSD) which involves a NLO correction suppressed by the small
reactor angle and show that the analytic results have good agreement with the numerical
results for these cases.

Abstract

Neutrinos with hierarchical masses and two large mixing angles may naturally
originate from sequential dominance (SD). Within this framework we present analytic
expressions for the neutrino mixing angles including the next-to-leading order (NLO)
and next-to-next-to-leading order (NNLO) corrections arising from the second lightest and
lightest neutrino masses. The analytic results for neutrino mixing angles in SD presented
here, including the NLO and NNLO corrections, are applicable to a wide class of models
and may provide useful insights when confronting the models with data from high precision
neutrino experiments. We also point out that for special cases of SD corresponding to
form dominance (FD) the NLO and NNLO corrections both vanish. For example we study
tri-bimaximal (TB) mixing via constrained sequential dominance (CSD) which involves
only a NNLO correction and tri-bimaximal-reactor (TBR) mixing via partially constrained
sequential dominance (PCSD) which involves a NLO correction suppressed by the small
reactor angle and show that the analytic results have good agreement with the numerical
results for these cases.
