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