Quantum Fisher Information as a Probe of Sterile Neutrino New Physics:Geometric Advantage of KM3NeT over IceCube

Baktiar Wasir Farooq, Bipin Singh Koranga, Aritro Chatterjee

We investigate a reported discrepancy between a high-energy neutrino detection at KM3NeT and its non-observation at IceCube, which suggests a statistical tension of up to 3.5 stand…
