Abstract
With the full BABAR data sample of 465 x 10(6) B (B) over bar pairs, we observe the decays B-+/- -> phi K-1(1270)(+/-) and B-+/- -> phi K-2*(1430)(+/-). We measure the branching fractions (6.1 +/- 1.6 +/- 1.1) x 10(-6) and (8.4 +/- 1.8 +/- 1.0) x 10(-6) and the fractions of longitudinal polarization 0.46(-0.13-0.07)(+0.12+0.06) and 0.80(-0.10)(+0.09) +/- 0.03, respectively. We also report on the B-+/- -> phi K-0*(1430)(+/-) decay branching fraction of (7.0 +/- 1.3 +/- 0.9) x 10(-6) and several parameters sensitive to CP violation and interference in the above three decays. Upper limits are placed on the B-+/- decay rates to final states with phi and K-1(1400)(+/-), K*(1410)(+/-), K-2(1770)(+/-), or K-2(1820)(+/-). Understanding the observed polarization pattern requires amplitude contributions from an uncertain source.
