We present a model-independent analysis of exclusive rare (Formula presented) decays, (Formula presented) The effect of possible new physics is written in terms of dimension-6 four-Fermi interactions. The lepton number violating scalar- and tensor-type interactions are included, and they induce (Formula presented) decays. We show systematically how the branching ratios and missing mass-squared spectrum depend on the coefficients of the four-Fermi interactions.
