Study of the Rare Charmless Hadronic B Meson Decays B-zero to phi K-zero and B-zero to K-star-plus pi-minus
This thesis describes the analyses of the rare charmless hadronic B meson decays B{sup 0} {yields} {phi}K{sup 0} and B{sup 0} {yields} K*{sup +}{pi}{sup -}, using 20.58 fb{sup -1} of e{sup +}e{sup -} data taken at the {Upsilon}(4S) resonance. The data were taken with the BABAR detector during its first run at the PEP-II asymmetric e{sup +}e{sup -} collider. Measurements of these modes using a counting technique are presented with the branching fractions {Beta}(B{sup 0} {yields} {phi}K{sup 0}) = (9.3 {+-} 3.4(stat.) {+-} 1.1(syst.)) x 10{sup -6} with a significance of 4.9{sigma}, and {Beta}(B{sup 0} {yields} K*{sup +}{pi}{sup -}) = (20.8 {+-} 9.3(stat.) {+-} 2.1(syst.)) x 10{sup -6} with a significance of 3.0{sigma}. For the latter, an upper limit of {Beta}(B{sup 0} {yields} K*{sup +}{pi}{sup -}) < 38.9 x 10{sup -6} was calculated at 90% confidence limit. The branching fraction of a calibration mode was measured using the same method, {Beta}(B{sup 0} {yields} D{sup -}{pi}{sup +}) = (3.59 {+-} 0.29(stat.) {+-} 0.35(syst.)) x 10{sup -3}.
