R Kumar, P Mishra, MK Behera, R Mohanta… - Physics Letters B, 2024 - Elsevier
This paper's novelty lies in introducing a hybrid scoto-seesaw model rooted in A 4 discrete
modular symmetry leading to several interesting phenomenological implications. The scoto …

Modular flavor models with positive modular weights: a new lepton model building

T Kobayashi, T Nomura, H Okada, H Otsuka - Journal of High Energy …, 2024 - Springer
A bstract We propose an interesting assignment of positive modular weights for fields in a
modular non-Abelian discrete flavor symmetry. By this assignment, we can construct inverse …

Neutrino Masses and Higher Degree Siegel Modular Forms

MR Devi - arXiv preprint arXiv:2401.16257, 2024 - arxiv.org
In this work, we have analyzed a neutrino model within the distinct framework of modular
forms with degree, $ g> 1$. This offers a more generalized scenario of modular forms which …

Neutrino phenomenology in the modular seesaw model
