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…
-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…
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…
Constraining the core radius and density jumps inside Earth using atmospheric neutrino oscillations
Anuj Kumar Upadhyay, Anil Kumar, Sanjib Kumar Agarwalla +1
Atmospheric neutrinos probe the interior of Earth using weak interactions, and provide information complementary to that of gravitational and seismic measurements. While passing th…
Improved measurements of the TeV-PeV extragalactic neutrino spectrum from joint analyses of IceCube tracks and cascades
R. Abbasi, M. Ackermann, J. Adams +424
The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks an…
