More on Non-standard Interaction at MINOS

Understand

We discuss about effects of the non-standard interaction of neutrinos with matter on the nu_e appearance search in the MINOS experiment.

• We consider the effects of the complex phase of the interaction and of the uncertainty on theta_23 also.
• We show that the oscillation probability can be so large that can not be explained by the ordinary oscillation.
• We show also how much constraints on the non-standard effects can be improved if the experiment does not observe nu_e appearance signal.
