Atmospheric Neutrinos: Status and Prospects

Understand

We present an overview of the current status of neutrino oscillation studies at atmospheric neutrino experiments.

• While the current data gives some tentalising hints regarding the neutrino mass hierarchy, octant of $\theta_{23}$ and $\delta_{CP}$, the hints are not statistically significant.
• We summarise the sensitivity to these sub-dominant three-generation effects from the next-generation proposed atmospheric neutrino experiments.
• We next present the prospects of new physics searches such as non-standard interactions, sterile neutrinos and CPT violation studies at these experiments.
