MODEL-INDEPENDENT ANALYSIS OF THE DECAY B-]K-)(L(+)+L()

We demonstrate that the Dalitz-distributions in energies of both unpol arized leptons, produced in the decays B --> K + l(+) + l(-) for l= e, mu, tau, can be a sensitive test for possible new physics beyond the Standard Model. We find measurable characteristics (including the pola rization of leptons as well) which are independent of all dirty non-pe rturbative physics needed in calculating the hadronic form factors. Su ch characteristics can be used to estimate the presence of possible no n-standard mechanisms in a model-independent manner. (C) 1998 Elsevier Science B.V. All rights reserved.
