Download or read book OBSERVATION OF EXCLUSIVE TWO BODY B DECAYS TO KAONS AND PIONS written by and published by . This book was released on 2003 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have studied two-body charmless hadronic decays of B mesons into the final states??, K?, and KK. Using 3.3 million B{bar B} pairs collected with the CLEO-II detector, we have made the first observation of the decays B° → K?−, B+ → K°?+, and the sum of B+ →?+?° and B+ → K+?° decays (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis presents the searches for two rare B meson decays: the radiative leptonic decay B+ -> l+ nu gamma (l = e, mu) and the flavor-changing neutral current B -> K(*) nu nubar. These searches use the full dataset collected by the BaBar experiment, which corresponds to almost 500 million BB pairs. After fully reconstructing the hadronic decay of one of the B mesons in Upsilon(4S) -> BB decays, evidence of B+ -> l+ nu gamma or B -> K(*) nu nubar is looked for in the rest of the event. No significant evidence of either signal decay is observed. Model-independent branching-fraction upper limits are set at BR(B ->e nu gamma)17 x10 {-6}, BR(B -mu nu gamma)24 x10 {-6}, and BR(B -l nu gamma)15.6 x10 {-6}, all at the 90% confidence level. These are currently the most stringent published upper limits for B+ - l+ nu gamma. In addition, branching-fraction upper limits are set at BR(B -> K+ nu nubar)3.7 x10 {-5}, BR(B - K0 nu nubar)8.0 x10 {-5}, BR(B - K*+ nu nubar)11.5 x10 {-5}, and BR(B - K*0 nu nubar)9.2 x10 {-5}, all at the 90% confidence level. For additional sensitivity to New Physics contributions, partial B - K(*) nu nubar branching-fraction upper limits are also determined over the full kinematic range." --

Available in PDF, EPUB and Kindle. Book excerpt: Based on a sample of approximately 500,000 hadronic Z° decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body exclusive charmless hadronic decays of B, B°, and B{sub s}° mesons. The precise tracking capabilities of the SLD detector provided for the efficient reduction of combinatoric backgrounds, yielding the most precise available limits for ten of these modes.

Available in PDF, EPUB and Kindle. Book excerpt: We discuss within the context of heavy-quark symmetry a program for performing model 226 independent tests of the factorization scenario proposed by Dugan and Grinstein for hadronic B-meson decays. Preliminary, model 226 dependent results for decays to a D or D* and one, two, or three pions are presented which indicate that the predictions of factorization are consistent with the present experimental situation. Our results suggest that such decays may not only provide a precision testing ground for factorization, but also an opportunity to study the properties of excited D mesons and to measure many of the universal form factors of heavy-quark symmetry (including ones not otherwise readily accessible).

Book excerpt: Using 22.7M B{bar B} events collected with the BABAR detector at SLAC, we present preliminary measurements of the branching fractions for charmless hadronic decays of B mesons into two-body, quasi two-body and three-body final states with pions, kaons, and? and a0 resonances. In the search for exclusive B° →??−?°, we measure?(B° →?{sup ±}(770)?{sup {-+}}) = (28.9 ± 5.4 ± 4.3) x 10−6, together with the relative asymmetry?{sub phys} = -0.04 ± 0.18 {+-} 0.02. We also set the upper limits on B° →?°(770)?°, non-resonant B° →?+?−?°, B° → a0{sup {+-}}(→??{sup {+-}})?{sup {-+}} and B° → K°{bar K}°.
