摘要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(-) -> omega pi(0), K*(892)(K) over bar, and K-2*(1430)(K) over bar. ( Charge-conjugate modes are included implicitly.) Significant signals of omega pi(0), K*(892)(0)(K) over bar (0), and K-2*(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 K-2*(1430)(0)(K) over bar (0) are found, and we set limits on the cross section ratios R-VP = sigma(B)(e(+)e(-)-> K*(892)K-0(0))/sigma(B)(e(+)e(-)-> K*(892)K--(+)) > 4.3, 20.0, and 5.4, and R-TP = sigma(B)(e(+)e(-) -> K-2*(1430)(0)(K) over bar (0))/sigma(B)(e(+)e(-)-> K-2*(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.
