Neutrino Mass Generation Theories: Unification to Anarchy

Delve into diverse Neutrino mass generation theories, from unified models to anarchic structures. Explore pressing questions, dataset fits, and exciting prospects in the field. Discover the origins and implications of small Majorana neutrino masses, double beta decay, and more. Uncover the role of Grand Unified Theories and gauge coupling unification in shaping our understanding of Neutrino masses. Dive into specific examples like Type I Seesaw and Tri-bimaximal Neutrino Mixing, examining fermion mass hierarchies and texture zeros in depth. Leave no stone unturned in this comprehensive exploration of Neutrino Mass Generation.
