| Abstract: | The exclusive B→K(*) e+ e- decays are studied in the topcolor-assisted technicolor model and in the minimal technicolor model. We find that the angular distribution and the dilepton mass distribution in B→K(*) e+ e- which can be reliably 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. |
