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+.

Available in PDF, EPUB and Kindle. Book excerpt: Using a large data sample of p{bar p} collisions at {radical}s = 1.96 TeV recorded by the CDF and D0 detectors operating at Fermilab Tevatron, the orbitally excited B mesons B{sub 1} and B*{sub 2} are observed directly as two separate states in fully reconstructed decays to B{sup (*)}{pi}. The masses and the mass differences between the states are presented. In the charm system, the orbitally excited D mesons D{sub 1} and D*{sub 2} are observed in fully reconstructed decays to D{sup (*)}{pi}. Measurements of the product branching rates of semileptonic decays B {yields} {bar D}**{mu}{sup +}{nu}{sub {mu}}X and their ratio are presented. They also present the observation of the semileptonic decays B{sub s} {yields} {mu}{nu}D**{sub s} where the excited D**{sub s} states are reconstructed in the mode D**{sub s} {yields} D*K{sub S}{sup 0}.

Download or read book First Observation of Fully Reconstructed B0 and Bs0 Decays into Final States Involving an Excited Neutral Charm Meson in LHCb written by Arnau Brossa Gonzalo and published by Springer Nature. This book was released on 2023-01-31 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest results on the branching fraction and phase space distribution of B0 and Bs0 decays into final states including excited neutral charm mesons. This work represents four years of research, and the book describes in detail all the necessary steps and techniques required to perform a physics analysis of the data recorded by the LHCb experiment in the years 2016–2018. Although the results presented in this book represent the first measurement of such decays, the text is written in a manner accessible to Ph.D. students and early career researchers. Thus, all the contents included in this book are described in a pedagogical way, including technical details that would allow the results to be reproduced in future. In addition to the methodology used to perform these measurements, the book also includes a description of the theoretical background required to interpret the results presented, as well as a technical description of the LHCb detector, which provided the data sample used in this study.

Download or read book Semileptonic Decays of B Mesons Into Excited Charm Mesons written by and published by . This book was released on 1992 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use the heavy quark effective theory to investigate the form factors that describe the semileptonic decays of a B meson into excited daughter mesons. For an excited daughter meson with charm, a single form factor is needed at leading order, while five form factors and two dimensionful constants are needed to order 1/m(sub)c in the heavy quark expansion. For non-charmed final states, a total of four form factors are needed at leading order. For the process B ->D^(*)Xlv, four form factors are also needed at leading order.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we compute, within in the context of a relativistic quark model, the Isgur-Wise functions for exclusive semileptonic $\bar B \to X_c$ decays, where $X_c$ is any charmed mesons with total spin $J=0,1,2$ or one of their first excited states. The relevant matrix elements are computed by a direct numerical integration, in coordinate space, of the convolution of the wave function of the $B$ meson at rest and the wave function of the $X_c$ meson, boosted according with its recoil factor. Our results are compared with other predictions found in the existing literature.

Available in PDF, EPUB and Kindle. Book excerpt: We have studied semileptonic B meson decays with a P-wave charm meson in the final state using 3.29 x 10[sup 6] B[bar B] events collected by the CLEO II detector at the Cornell Electron-positron Storage Ring. We find a value for the exclusive semileptonic product branching fraction:[Beta](B[sup -][yields] D[sub 1][sup 0][ell][sup -][bar[nu]][sub[ell]])[Beta](D[sub 1][sup 0][yields] D*[sup+][pi][sup -])= (0.373[+-] 0.085[+-] 0.052[+-] 0.024)% and an upper limit for[Beta](B[sup -][yields] D*[sub 2][sup 0][ell][sup -][bar[nu]][sub[ell]])[Beta](D*[sub 2][sup 0][yields] D*[sup+][pi][sup -])

Download or read book Soft Pion Emission in Semileptonic B-meson Decays written by and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of semileptonic decays of B mesons with the emission of a single soft pion is presented in the framework of the heavy-quark limit using an effective Lagrangian which implements chiral and heavy-quark symmetries. The analysis is performed at leading order of the chiral and inverse heavy mass expansions. In addition to the ground state heavy mesons some of their resonances are included. The estimates of the various coupling constants and form factors needed in the analysis are obtained using a chiral quark model. As the main result, a clear indication is found that the 0 and 1+ resonances substantially affect the decay mode with a D{sup *} in the final state, and a less dramatic effect is also noticed in the D mode. An analysis of the decay spectrum in the D{sup *}-?2 invariant mass is carried out, showing the main effects of including the resonances. The obtained rates show promising prospects for studies of soft pion emission in semileptonic B-meson decays in a B-meson factory where, module experimental cuts, about 105 such decays in the D meson mode and 104 in the D{sup *} mode could be observed per year.

Download or read book Excited Charm Mesons in Semileptonic B Decay and Their Contributions to a Bjorken Sum Rule written by and published by . This book was released on 1991 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has recently been shown that hadrons containing a single heavy quark exhibit a new flavor-spin symmetry of QCD. We exploit this symmetry to obtain model independent predictions for the fourteen form factors in weak decays from the ground state pseudoscalar meson P(sub)Q(sub)i of a heavy quark Q(sub)i to the low-lying positive parity excited states of a heavy quark Q(sub)j in terms of two universal functions of momentum transfer. These predictions are of interest in the study of B -> D*(sub)2(2460), D(sub)1(~2460), D(sub)1(2420), and D*(sub)0(~2420) semileptonic decays. We also discuss the connection between these results and the slope of the function Xi (which determines the B->D and B->D* transition form factors) given by a heavy quark sum rule suggested by Bjorken.
