摘要：

We study the contributions of the nonstandard neutrino interactions to the rare meson decays of K+->pi(+)nu(v) over bar and D+->pi(+)nu(v) over bar. We show that both decays could provide strong constraints on the free parameters in the nonstandard neutrino interactions. We point out that the branching ratio of D+->pi(+)nu(v) over bar could be at the level of 10(-8).
