@article{Novichkov2019ModularAS, title={Modular A5 symmetry for flavour model building}, author={Pavel Novichkov and J. T. Penedo and Serguey T. Petcov and Arsenii Titov}, journal={Journal of High Energy Physics}, year={2019}, volume={2019}, pages={1-34} }

A bstractIn the framework of the modular symmetry approach to lepton flavour, we consider a class of theories where matter superfields transform in representations of the finite modular group Γ5 ≃ A5. We explicitly construct a basis for the 11 modular forms of weight 2 and level 5. We show how these forms arrange themselves into two triplets and a quintet of A5. We also present multiplets of modular forms of higher weight. Finally, we provide an example of application of our results…
