We study non-standard interactions (NSIs) at reactor neutrino experiments, and in particular, the mimicking effects on theta_13. We present generic formulas for oscillation probabilities including NSIs from sources and detectors. Instructive mappings
between the fundamental leptonic mixing parameters and the effective leptonic mixing parameters are established. In addition, NSI corrections to the mixing angles theta_13 and theta_12 are discussed in detailed. Finally, we show that, even for a vanishing theta_13, an oscillation phenomenon may still be observed in future short baseline reactor neutrino experiments, such as Double Chooz and Daya Bay, due to the existences of NSIs.
We investigate non-standard neutrino interactions (NSIs) in the triplet seesaw model featuring non-trivial correlations between NSI parameters and neutrino masses and mixing parameters. We show that sizable NSIs can be generated as a consequence of a
nearly degenerate neutrino mass spectrum. Thus, these NSIs could lead to quite significant signals of lepton flavor violating decays such as mu^- to e^- u_e anti u_mu and mu^+ to e^+ anti u_e u_mu at a future neutrino factory, effects adding to the uncertainty in determination of the Earth matter density profile, as well as characteristic patterns of the doubly charged Higgs decays observable at the Large Hadron Collider.
