摘要： We report a search for the rare charmless decay B+→K¯¯¯¯¯∗0K∗+ using a data sample of 772×106 BB¯ pairs collected at the Υ(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 as B(B+→K¯¯¯¯¯∗0K∗+)<1.31×10−6.
