چکیده انگلیسی
We expound in detail the degeneracy between the octant of θ23 and flavor-changing neutral-current non-standard interactions (NSI's) in neutrino propagation, considering the Deep Underground Neutrino Experiment (DUNE) as a case study. In the presence of such NSI parameters involving the eâμ (εeμ) and eâÏ (εeÏ) flavors, the νμâνe and ν¯μâν¯e appearance probabilities in long-baseline experiments acquire an additional interference term, which depends on one new dynamical CP-phase Ïeμ/eÏ. This term sums up with the well-known interference term related to the standard CP-phase δ creating a source of confusion in the determination of the octant of θ23. We show that for values of the NSI coupling (taken one at-a-time) as small as few% (relative to the Fermi coupling constant GF), and for unfavorable combinations of the two CP-phases δ and Ïeμ/eÏ, the discovery potential of the octant of θ23 gets completely lost.
