Non-standard interaction effects at reactor neutrino experiments

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), all Oscillation phenomenon may still be observed ill future short baseline reactor neutrino experiments, such as Double Chooz and Daya Bay, due to the existences of NSIs.
