Degeneracy between ${\theta }_{23}$ octant and neutrino non-standard interactions at DUNE

Sanjib Kumar Agarwalla, Sabya Sachi Chatterjee, Antonio Palazzo

We expound in detail the degeneracy between the octant of ${\theta }_{23}$ and flavor-changing neutral-current non-standard interactions (NSI's) in neutrino propagation, considering the De…
