Probing a Four Flavour vis-a-vis Three Flavour Neutrino Mixing for UHE Neutrino Signals at a 1 ${\mathrm{Km}}^2$ Detector

Madhurima Pandey, Debasish Majumdar, Amit Dutta Banik

We consider a four flavour scenario for the neutrinos where an extra sterile neutrino is introduced with the three families of active neutrinos and study the deviation from three f…
