摘要: We discuss ways to explore non-standard interactions (NSI) which neutrinos may possess by expressing them as effective four Fermi operators with coefficient of the order (M_{W} / M_{NP})^2 ~0.01 (0.0001) for energy scales new physics M_{NP} ~1 (10) TeV. Neutrino Factory is a prime candidate such apparatus that can reach extreme precision. I describe two detector setting, one at baseline L~3000 km and other L~7000 km, able solve notorious theta_{13}-NSI confusion, possibly also two-phase confusion. The resultant sensitivities off-diagonal NSI elements \epsilon's are excellent, |\epsilon_{e tau}| \simeq few \times10^{-3} mu}| \times10^{-4}. Our results suggest picture neutrino factory hunting machine while keeping its potential precision measurement lepton mixing parameters. Sensitivities T2KK related settings discussed.
