Abstract
The first search for double charged charmoniumlike state production in 1S and 2S decays and in e e -annihilation at ffiffi ffi s p 10.52, 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 1S and 2S decays [B1S;
