Query: Non-standard interactions versus planet-scale neutrino oscillations   The low-energy threshold and the large detector size of Precision IceCube
Next Generation Upgrade (PINGU) can make the study on neutrino oscillations
with a planet-scale baseline possible. In this task, we consider the
configuration that neutrinos are produced at CERN and detected in the PINGU
detector, as a benchmark. We discuss its sensitivity of measuring the size of
non-standard interactions (NSIs) in matter, which can be described by the
parameter $\epsilon_{\alpha\beta}$ ($\alpha$ and $\beta$ are flavors of
neutrinos). We find that the CERN-PINGU configuration improves
$\tilde{\epsilon}_{\mu\mu}\equiv\epsilon_{\mu\mu}-\epsilon_{\tau\tau}$ and
$\epsilon_{\mu\tau}$ significantly compared to the next-generation accelerator
neutrino experiments. Most of degeneracy problems in the precision measurements
can be resolved, except the one for $\tilde{\epsilon}_{\mu\mu}\sim-0.035$.
Moreover, we point out that this configuration can also be used to detect the
CP violation brought by NSIs. Finally, we compare the physics potential in this
configuration to that for DUNE, T2HK and P2O, and find that the CERN-PINGU
configuration can significantly improve the sensitivity to NSIs.
