Measurement of rare decay of B → K(∗)l+l− in the topcolor and the technicolor models Original Research Article

We study the exclusive B → K(∗)l+l− decays in the topcolor-assisted technicolor model I and the one-generation technicolor model. The angular distribution and the dilepton mass distribution in B → K(∗)l+l−, which can be reliable predicted in the large dilepton mass region, are very sensitive to the actual form of the new interaction. This provides a good test to physics beyond the standard model.
