Journal Article

Using data samples of 89 fb-1, 703 fb-1, and 121 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider at center-of-mass energies 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, we study the exclusive reactions e +e-→ωπ0, K*(892)K̄, and K2*(1430)K̄. (Charge-conjugate modes are included implicitly.) Significant signals of ωπ0, K*(892)0K ̄0, and K2*(1430)-K+ are observed for the first time at these energies, and the energy dependencies of the cross sections are presented. On the other hand, no significant excesses for K *(892)-K+ and K2*(1430) 0K ̄0 are found, and we set limits on the cross section ratios RVP=σB(e+e-→K *(892) 0K̄0)σB(e +e-→K*(892)-K +)>4.3, 20.0, and 5.4, and RTP= σB(e+e-→K2*(1430)0K ̄0)σB(e+e -→K2*(1430)-K+)<1.1, 0.4, and 0.6, for center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.876 GeV, respectively, at the 90% C.L. © 2013 American Physical Society.
