Query: Searching for Novel Neutrino Interactions at NOvA and Beyond in Light of
  Large theta_13   We examine the prospects of probing nonstandard interactions (NSI) of
neutrinos in the e-tau sector with upcoming long-baseline nu_mu -> nu_e
oscillation experiments. First conjectured decades ago, neutrino NSI remain of
great interest, especially in light of the recent 8B solar neutrino
measurements by SNO, Super-Kamiokande, and Borexino. We observe that the recent
discovery of large theta_13 implies that long-baseline experiments have
considerable NSI sensitivity, thanks to the interference of the standard and
new physics conversion amplitudes. In particular, in some parts of NSI
parameter space, the upcoming NOvA experiment will be sensitive enough to see ~
3sigma deviations from the SM-only hypothesis. On the flip side, NSI introduce
important ambiguities in interpreting NOvA results as measurements of
CP-violation, the mass hierarchy and the octant of theta_23. In particular,
observed CP violation could be due to a phase coming from NSI, rather than the
vacuum Hamiltonian. The proposed LBNE experiment, with its longer ~ 1300 km
baseline, may break many of these interpretative degeneracies.
