Abstract

We report a search for the rare charmless decay B+→K¯∗0K∗+ using a data sample of 772×106 BB¯ pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e-collider. No statistically significant signal is found and a 90% confidence-level upper limit is set on the decay branching fraction of B(B+→K¯∗0K∗+)<1.31×10-6.
