Constraints on non-standard flavor-dependent interactions from Superkamiokande and Hyperkamiokande

We investigate the constraint on the flavor-dependent neutral current Non-Standard Interactions in propagation from atmospheric neutrino experiments Superkamiokande and Hyperkamiokande. With the ansatz where the parameters which have strong constraints from other experiments are neglected, we show how these experiments put constraints on the remaining parameters of the Non-Standard Interactions.
