Book Description
An upper limit has been extracted, at the 90% C.L, for the rare charmless hadronic B meson decay B ± → a0(980)±?0, where a0(980)± →??± and ?????????? or ???????? ?+?-?0. The analysis was based on a sample of approximately 340.7 fb-1 of data taken at the (4S) resonance with the BABAR detector at the PEP-II e+e- collider at SLAC from May 1999 to August 2006. The sample contains (379.9 ± 4.2) million B$ar{B}$ pairs.

An upper limit has been extracted, at the 90% C.L, for the rare charmless hadronic B meson decay B ± → a0(980)±[pi]0, where a0(980)± →[eta][pi]± and [eta]→[gamma][gamma] or [eta]→ [pi]+[pi]-[pi]0.

Book Description
We present preliminary results of several searches for rare charmless hadronic decays of the B meson using data collected by the BABAR detector at the Stanford Linear Accelerator Center's PEP-II storage ring. We search for the decays hh−, h+h−h+, h+h−?°, X°h+, and X°K{sub S}°, where h =? or K, and X° =?' or?. In a sample of 8.8 million B{bar B} decays they measure the branching fractions. They calculate upper limits for the modes without a significant signal.

Book Description
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 -])

Book Description
Preliminary results are presented on a search for several exclusive charmless hadronic B decays, from data collected by the BABAR detector near the [Upsilon](4S) resonance. These include two-body decay modes h{sup {+-}}h{sup {-+}}, three-body decay modes with final states h{sup {+-}}h{sup {-+}}h{sup {+-}} and h{sup {+-}}h{sup {-+}}[pi]°, and quasi-two-body decay modes with final states X°h and X°K{sub s}°, where h = [pi] or K and X° = [eta]' or [omega]. The measurement of branching fractions for four decay modes, and upper limits for nine modes are presented.
