This book was released on 2006 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors searched for decays of the type B{sub (s)}{sup 0} {yields} h{sup +}h{prime}{sup -} (where h, h{prime} = K or {pi}) in a sample corresponding to 180 pb{sup -1} of p{bar p} collisions at {radical}s = 1.96 TeV, collected by the upgraded Collider Detector at the Fermilab Tevatron. A total signal of approximately 900 events was reconstructed, and the relative branching fractions ({Beta}) of each decay mode were determined with a likelihood fit.

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.

Download or read book Measurements of Branching Fractions and CP-Violating Asymmetries in B-Meson Decays to the Charmless Two-Body States K[sup 0]pi+, K-bar[sup 0]K[sup +], and K[sup 0]K-bar[sup 0]. written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present preliminary measurements of the branching fraction and the CP-violating charge asymmetry in the B[sup +] --> K[sup 0][pi][sup +] decay, and a preliminary measurement of the branching fraction of the B[sup 0] --> K[sup 0][bar K][sup 0] decay. No evidence of direct CP violation in the B[sup +] --> K[sup 0][pi][sup +] mode is observed. The B[sup 0] --> K[sup 0][bar K][sup 0] measurement constitutes the first observation of this decay channel: the probability of obtaining the result assuming the null-signal hypothesis is 3.4 x 10[sup -6]. The authors have also searched for the B[sup +] --> [bar K][sup 0]K[sup +] decay and set an upper limit on its branching fraction at 2.35 x 10[sup -6] at the 90% C.L. The branching-fraction measurements reported here are consistent with previous measurements of the same quantities, but are extracted from a data sample larger by a factor of 2.6.

This book was released on 2006 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors search for decays of the type B{sub (s)}° → h+h'− (where h,h' = K or ?) in 180 pb−1 of data collected by the CDF II detector at the Fermilab Tevatron. They observe the new mode B{sub s}° → K+K− with a yield of 236 ± 32 events, corresponding to (f{sub s}/f{sub d}) x ?(B{sub s}° → K+K−)/?(B° → K+?−) = 0.46 ± 0.08(stat.) ± 0.07(syst.), where f{sub s}/f{sub d} is the ratio of production fractions of B{sub s}° and B°. They find results in agreement with world averages for the modes B° → ?+?− and B° → K+?−, and set the following upper limits at 90% CL: ?(B° → K+K−)
Book Synopsis Particle Physics Reference Library by : Herwig Schopper
Download or read book Particle Physics Reference Library written by Herwig Schopper and published by Springer Nature. This book was released on 2020 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

The analysis uses a data sample with an integrated luminosity of 429.0 fb-1, recorded by the BABAR detector at the PEP-II asymmetric B Factory. This sample corresponds to 470.9 ±} 2.8 million B$\bar{B}$ pairs.

Download or read book Measurements of the Branching Fractions of Charmless Three-Body Charged B Decays written by and published by . This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary results of searches for charged B mesons decaying into the charmless three-body final states h{sup ±} h{sup {-+}} h{sup ±}, where h = [pi] or K, using 51.5 fb−1 of data collected at the [Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. No assumptions are made about intermediate resonances. We measure the branching fractions [Beta](B{sup ±} 2!K{sup ±} [pi]{sup {-+}} [pi]{sup {+-}}) = (59.2 {+-} 4.7 {+-} 4.9) x 10−6 and [Beta](B{sup {+-}} 2!K{sup {+-}} K{sup {-+}} K{sup {+-}}) = (34.7 {+-} 2.0 {+-} 1.8) x 10−6, where the first error is statistical and the second error is systematic. In the same study, we do not observe significant signals for the final states B{sup {+-}} 2![pi]{sup {+-}} [pi]{sup {-+}} [pi]{sup {+-}} and B{sup {+-}} 2!K{sup {+-}} K{sup {-+}} [pi]{sup {+-}}, and therefore provide the 90% confidence upper limits [Beta](B{sup {+-}} 2![pi]{sup {+-}} [pi]{sup {-+}} [pi]{sup {+-}})

Book excerpt: The high cross-section for the production of b quarks at the Tevatron hadron collider make it an ideal place to search for rare B meson species and very low branching fraction decay modes of the more common B mesons. This paper reports the recent discovery of the Bc meson by the CDF collaboration. It also discusses the observation of rare B meson final states involving?(2S) mesons and searches for ultra-rare decays such as B 2!??−
