Testing neutrino flavor models
Abstract
Finding a rationale behind the observed pattern of neutrino mixings has been at the focus of neutrino flavor model building. Many different approaches have been put forward including models based on symmetries. Among the most predictive models based on symmetries are models which predict not only the mixing parameters but also correlations between them. These mixing sum rules allow to probe flavor models in the future. In this white paper we collect the predictions for the mixing parameters from flavor models based on discrete symmetries broken to certain residual symmetries of the lepton mass matrices and from models with modular symmetries to contrast them with bounds from current and future oscillations experiments.
