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