Abstract:	Using 535 X 10(6) B-meson pairs collected by the Belle detector at the KEKB e(+)e(-) collider, we measure branching fractions of (7.16 +/- 0.10(stat) +/- 0.60(syst) X 10(-4) for B(+) -> J/psi K(+) pi(+) pi(-) and (4.31 +/- 0.20(stat) +/- 0.50(syst)) X 10(-4) for B(+) -> psi' K(+) pi(+) pi(-). We perform amplitude analyses to determine the resonant structure of the K(+) pi(+) pi(-) final state in B(+) -> J/psi K(+) pi(+) pi(-) and B(+) -> psi' K(+) pi(+) pi(-) and find that the K(1)(1270) is a prominent component of both decay modes. There is significant interference among the different intermediate states, which leads, in particular, to a striking distortion of the rho line shape due to the omega. Based on the results of the fit to the B(+) -> J/psi K(+) pi(+) pi(-) data, the relative decay fractions of the K(1)(1270) to K rho, K omega, and K(892)pi are consistent with previous measurements, but the decay fraction to K(0)()(1430) is significantly smaller. Finally, by floating the mass and width of the K(1)(1270) in an additional fit of the B(+) -> J/psi K(+) pi(+) pi(-) data, we measure a mass of (1248.1 +/- 3.3(stat) +/- 1.4(syst)) MeV/c(2) and a width of (119.5 +/- 5.2(stat) +/- 6.7(syst)) MeV/c(2) for the K(1)(1270).
