Available in PDF, EPUB and Kindle. Book excerpt: Using 383 million B{bar B} pairs from the BABAR data sample, they report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K{bar K}* or [eta][pi][pi] final states with mass in the range (1.2-1.8) GeV/c2. They observe a significant enhancement at the low K{bar K}* invariant mass which is interpreted as B 2K, find evidence for the decay B+ 2K+, and place upper limits on the decays B+ 2K+, B+ 2!f1(1285)K+, B+ 2!f1(1420)K+, and B+ 2K+.

This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the results of searches for B decays to charmless two-body final states containing [eta] or [omega] mesons, based on 20.7 fb−1 of data collected with the BABAR detector. We find the branching fractions [Beta](B 2![eta] K) = (70 ± 8 ± 5) x 10−6, [Beta](B° 2![eta] K°) = (42−11{sup +13} ± 4) x 10−6, and [Beta](B+ 2![omega][pi]+) = (6.6{sub -1.8}{sup +2.1} ± 0.7) x 10−6 where the first error quoted is statistical and the second systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are [Beta](B° 2![omega] K°)

Download or read book On Decays of B Mesons to a Strange Meson and an Eta Or Eta' Meson at Babar written by and published by . This book was released on 2009 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe studies of the decays of B mesons to final states [eta]K{sup *}(892), [eta]K{sup *}0(S-wave), [eta]K{sup *}2(1430), and [eta]'K based on data collected with the BABAR detector at the PEP-II asymmetric-energy ee− collier at the Stanford Linear Accelerator Center. We measure branching fractions and charge asymmetries for the decays B 2![eta]K{sup *}, where K{sup *} indicates a spin 0, 1, or 2 K[pi] system, making first observations of decays to final states [eta]K{sup *0}0(S-wave), [eta]K{sup *+}0 (S-wave), and [eta]K{sup *0}2(1430). We measure the time-dependent CP-violation parameters S and C for the decays B° 2![eta]'K°, observing CP violation in a charmless B decay with 5[sigma] significance considering both statistical and systematic uncertainties.
Book Synopsis Studies on B-Meson Decays by : Hluf Negash Gebrehiwet
Download or read book Studies on B-Meson Decays written by Hluf Negash Gebrehiwet and published by LAP Lambert Academic Publishing. This book was released on 2014-12-18 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is written by Hluf Negash which studies the decays of B-meson in the framework of Bethe-Salpeter equation under covariant instantaneous ansatz. The analysis of this study gives important information about the internal structure of hadrons. The prediction of the properties of strongly interacting particles using the mesonic and baryonic sectors is of great importance since these hadrons can be easily produced in experiments and hence the theoretical predictions can be veri ed.
Book Synopsis Study of B Meson Decays to Ppbarh Final States by : Tetiana B. Hryn'ova
Download or read book Study of B Meson Decays to Ppbarh Final States written by Tetiana B. Hryn'ova and published by . This book was released on 2006 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: B mesons are unique among well-established non-quarkonium mesons in their ability to decay into baryons. Baryonic B decays offer a wide range of interesting areas of study: they can be used to test our theoretical understanding of rare decay processes involving baryons, search for direct CP violation and study low-energy QCD. This thesis presents measurements of branching fractions and a study of the decay dynamics of the charmless three-body decays of B meson into p{bar p}h final states, where h = {pi}{sup +}, K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}. With a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BaBar detector, we report the first observation of the B {yields} p{bar p}K*{sup 0} decay, and provide improved measurements of branching fractions of the other modes. The distribution of the three final-state particles is of particular interest since it provides dynamical information on the possible presence of exotic intermediate states such as the hypothetical pentaquark states {Theta}*{sup ++} and {Theta}{sup +}in the m{sub pK{sup +}} and m{sub pK{sub S}{sup 0}} spectra, respectively, or glueball states (such as the tensor glueball f{sub J}(2220)) in the m{sub p{bar p}} spectrum. No evidence for exotic states is found and upper limits on the branching fractions are set. An enhancement at low p{bar p} mass is observed in all the B {yields} p{bar p}h modes, and its shape is compared between the decay modes and with the shape of the time-like proton form factor. A Dalitz plot asymmetry in B {yields} p{bar p}K{sup +} mode suggests dominance of the penguin amplitude in this decay and disfavors the possibility that the low mass p{bar p} enhancement originates from the presence of a resonance below threshold (such as the recently seen baryonium candidate at 1835 MeV/c{sup 2}). We also identify decays of the type B {yields} X{sub c{bar c}}h {yields} p{bar p}h, where h = K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}, and X{sub c{bar c}} = {eta}{sub c} or J/{psi}. In particular, we report on the evidence of the B {yields} {eta}{sub c}K*{sup +} decay and provide a measurement of the width of {eta}{sub c}.
