dc.description.abstract	We report results of a search for B --> tau nu in a sample of 9.7 x 10(6) charged B meson decays. We exclusively reconstruct the companion B decay to suppress background. We set an upper limit on the branching fraction B(B --> tau nu) < 8.4 X 10(-4) at 90% confidence level, We also establish B(B+/- --> K+/- nu <(nu )over bar >) < 2.4 X 10(-4) at 90% confidence level.
