In such a framework, the main drawback of the SO(10) prototype-in particular, the generic tension among the gauge unification constraints and the absolute neutrino mass scale-is alleviated, and a simple yet potentially realistic and testable scenario emerges.", optnote="WOS:000332175700004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1715), last updated on Fri, 04 Apr 2014 00:22:46 +0000", issn="1550-7998", doi="10.1103/PhysRevD.89.055003", opturl="http://arxiv.org/abs/arXiv:1310.0914", opturl="https://doi.org/10.1103/PhysRevD.89.055003", archivePrefix="arXiv", eprint="arXiv:1310.0914", language="English" }
