Up-down atmospheric neutrino flux asymmetry predictions for various neutrino oscillation scenarios

We compute up-down asymmetries for atmospheric neutrino induced electron and muon events in the SuperKamiokande detector for the following neutrino oscillation models: (A) maximally mixed ${\nu }_{\mu }-{\nu }_{\tau }$ or $\nu_{\mu}

• \nu_s$,(B)maximallymixed$\nu_{\mu} - \nu_e$, © threefold maximal mixing between ${\nu }_e,{\nu }_{\mu }$ and ${\nu }_{\tau }$, and (D) neutrino oscillations via Equivalence Principle or Lorentz invariance violation. We emphasise the role of different momentum cuts.
