Study of $K^0_S$ pair production in single-tag two-photon collisions
Abstract
We report a measurement of the cross section for pair production in single-tag two-photon collisions, , for up to 30 GeV, where is the negative of the invariant mass squared of the tagged photon. The measurement covers the kinematic range 1.0 GeV < W < 2.6 GeV and for the total energy and kaon scattering angle, respectively, in the center-of-mass system. These results are based on a data sample of 759 fb collected with the Belle detector at the KEKB asymmetric-energy collider. For the first time, the transition form factor of the meson is measured separately for the helicity-0, -1, and -2 components and also compared with theoretical calculations. Finally, the partial decay widths of the and mesons are measured as a function of .
