  "description": "# CLASS with self-interacting neutrinos\n\n\nThis is a modified version of the CLASS code v3.1 (see http://class-code.net and https://github.com/lesgourg/class_public). It computes the interaction rate of resonant neutrino self-interactions.\n\n\nIt computes the neutrino distribution pertubations at linear order.\n\n\nThe implementation is based on:\n\n\nhttps://arxiv.org/abs/2303.12792\n\n\n----------------------------------------\n\n\n## Implementation\n\n\n**Resonant neutrino self-interactions:**\n\n\nWe modified the Boltzmann equations in the background and perturbation modules, to account for resonant neutrino self-interactions as presented in arXiv:2309.03941. We use precomputed interaction rates (in this code you compute new ones using the resonance.py script) you will find the precomputed files in the folder tables_Gamma_resonance.\n\n\n## Running this code\n\n\nTu run the code, you need to set the see the example.ini file. Additionaly, You can find example python scripts in the folder resonance_scripts.\n\n\n-------------------------------------------\n\n\n## Using this code\n\n\nIf you use the resonant neutrino self-interactions implementation please cite https://arxiv.org/abs/2303.12792 and https://arxiv.org/abs/2506.07994.\n\n\n------------------------------------------",
