Deep Earth imaging through neutrino and seismic tomography
Sanjib Kumar Agarwalla, Arjun Datta, Amol Dighe +2
This article is a report on the Deep Earth Neutrino + Seismic Imaging and TomographY (DENSITY 2026) mini-workshop, held on 23--24 February 2026 in the Department of Earth and Clima…
New constraints on non-unitary neutrino mixing from 8 years of IceCube DeepCore atmospheric neutrino data
Sharmistha Chattopadhyay, Anil Kumar, Sanjib Kumar Agarwalla
The mixing between flavor and mass eigenstates of active neutrinos is described by a unitary matrix. However, the presence of additional heavy sterile neutrino states ca…
Constraints on long-range neutrino interactions from a variety of symmetries using atmospheric neutrinos at IceCube DeepCore
Gopal Garg, J Krishnamoorthi, Anil Kumar +1
Neutrino oscillation experiments provide a unique probe to search for the physics beyond the Standard Model. In this work, we search for a broad class of anomaly-free flavor-depend…
-free constraints on NSI parameters and using high-purity CC events at IceCube DeepCore
J Krishnamoorthi, Anil Kumar, Sanjib Kumar Agarwalla
Atmospheric neutrinos provide a unique avenue to probe theories beyond the Standard Model (BSM) over a wide range of energies and path lengths. The theory of nonstandard interactio…
First Constraints on Long-Range Neutrino Interactions using IceCube DeepCore
Gopal Garg, J Krishnamoorthi, Anil Kumar +1
We present the first search for new flavor-dependent long-range interactions (LRI) of neutrinos using publicly available 8 years of high-purity CC data from IceCube DeepCore.…
