Abstract
For the first time we search for the in at , 10.58, and 10.867 GeV with data samples of , , and , respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant signal is observed in the mass range between 3.8 and . The upper limit at 90% confidence level on the product of the Born cross section for and branching fraction for is determined to be at near 10.6 GeV.
