Neutrino Mass Sum Rules from Modular ${\mathcal{A}}_4$ Symmetry

Salvador Centelles Chuliá, Ranjeet Kumar, Oleg Popov +1

Modular symmetries offer a dynamic approach to understanding the flavour structure of leptonic mixing. Using the modular ${\mathcal{A}}_4$ flavour symmetry integrated in a type-II se…
