Flavour Symmetry Embedded - GLoBES (FaSE-GLoBES)

Abstract

Neutrino models based on flavour symmetries provide a natural way to explain the origin of tiny neutrino masses. At the dawn of precision measurements of neutrino oscillation parameters, neutrino mass models can be constrained and examined by on-going and up-coming neutrino experiments. We present a supplemental tool Flavour Symmetry Embedded (FaSE) for General Long Baseline Experiment Simulator (GLoBES), and it is available on https://github.com/tcwphy/FASE_GLoBES. It can translate the neutrino mass model parameters into standard neutrino oscillation parameters and offer prior functions in a user-friendly way. We demonstrate the robustness of FaSE-GLoBES with four examples on how the model parameters can be constrained and whether the model is excluded by an experiment or not. We wish that this toolkit will facilitate the study of new neutrino mass models. Program summaryProgram title: FaSECPC Library link to program files:https://doi.org/10.17632/23bnpf2vps.1Developer’s repository link:https://github.com/tcwphy/FASE_GLoBESLicencing provisions: GNU General Public Licence 3Programming language: C/C++Nature of problem: The FaSE package serves to provide a toolkit for GLoBES for testing flavour symmetry models in neutrino oscillation experiments.Solution method: Two files are provided in FaSE: ‘FaSE_GLoBES.c’ and ‘model-input.c’. The function of ‘FaSE_GLoBES.c’ is to simulate the probability profile and implement the prior values for standard neutrino oscillation parameters, which are translated from the model parameters given by the user. While ‘FaSE_GLoBES.c’ does not need any modification, the user-defined input, which includes the model set up and any restrictions on the model parameters, are defined in ‘model-input.c’.Additional comments including restrictions and unusual features: This toolkit is not a standalone program, but it requires an installation of GLoBES version 3.0.0 or higher.
