Title: 	Testing Flavor Changing Neutrino Interactions in Long Baseline
	Experiments

We have investigated the possibility of discerning mass from flavor
changing neutrino interactions induced $\nu_\mu \to \nu_\tau$
oscillations in the long baseline neutrino experiments K2K and
MINOS. We have found that for virtually any value of the flavor
conserving parameter $\epsilon^\prime$ it will be possible to,
independently, distinguish these two mechanisms at K2K, if the flavor
changing parameter $\epsilon$ is in the range $\epsilon \gsim 0.77$,
and at MINOS, if $\epsilon \gsim 0.2$. Moreover, if K2K measures a
depletion of the expected $\nu_\mu$ flux then MINOS will either
observe or discard completely flavor changing neutrino oscillations
