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…
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 DeepCor…
Stringent constraints on non-standard neutrino interactions using high-purity CC events in IceCube DeepCore
J Krishnamoorthi, Anil Kumar, Sanjib Kumar Agarwalla
The neutral-current (NC) non-standard interactions (NSI) of neutrinos with fermions can modify the flavor oscillations of atmospheric neutrinos as they propagate through the Earth.…
Probing Earth's core using atmospheric neutrino oscillations in the presence of NSI at INO-ICAL
Krishnamoorthi J, Anuj Kumar Upadhyay, Anil Kumar +1
Neutrinos can serve as a complementary and independent tool to gravitational and seismic studies in exploring the interior of Earth, thanks to their unique properties: extremely lo…
