Abstract
The first search for double charged charmoniumlike state production in and decays and in annihilation at , 10.58, and 10.867 GeV is conducted using data collected with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant signals are observed in any of the studied modes, and the 90% credibility level upper limits on their product branching fractions in and decays [ (, , )] and the product of Born cross section and branching fraction for () at , 10.58, and 10.867 GeV are determined. Here, refers to the and observed in the final state, the and in the final state, and the and in the final state.
