Measurement of , , and nonresonant production via two-photon collisions
Abstract
We report the measurement of with decays to and using of data collected with the Belle detector at the KEKB asymmetric-energy collider. The mass and width are measured to be and , respectively. First observation of with a significance of including systematic error is obtained, and the mass is measured to be . The products of the two-photon decay width and branching fraction ( ) of decays to are determined to be for and for . The cross sections for and are measured for the first time.
