New Constraints on Neutrino-Dark Matter Interactions: A Comprehensive Analysis
P. S. Bhupal Dev, Doojin Kim, Deepak Sathyan +2
We present a comprehensive analysis of the interactions of neutrinos with the dark sector within the simplified model framework. We first derive the exact analytic formulas for the…

No Hiding in the Dark: Cosmological Bounds on Heavy Neutral Leptons with Dark Decay Channels
P. S. Bhupal Dev, Quan-feng Wu, Xun-Jie Xu
Heavy neutral leptons (HNLs) are well-motivated new physics candidates. The mixing of sub-GeV HNLs with active neutrinos is severely constrained by cosmology. In particular, the su…

Neutrino Theory Overview
P. S. Bhupal Dev
The neutrino sector is the least known in the Standard Model. We briefly review the open questions in neutrino physics and the future experimental prospects of answering them. We a…
