    An overview of exclusive two-body and three-body baryonic B decays is given. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest. Other decays Up: Decays Previous: Weak decays of charm Contents Weak decays of bottom hadrons. Some exclusive branching ratios now are known for decays. In this version, the,, and therefore appear in a similar vein to the one outlined above for and above. That is, all leptonic channels and all hadronic two-body decay channels are explicitly listed, while hadronic channels with three or more.

    Recently, there has been a remarkable progress in the study of exclusive charmless bottom meson decays both experimentally and theoretically. Ex-perimentally, CLEO [1] has discovered many new two body decay modes B→ η ′K±, ηK0, π ±K∓,π0K±, ρ0π, ωK± (1) and found a possible evidence for B→ φK∗. Moreover, CLEO has provided. Abstract Along with the running of Large Hadron Collider (LHC) located at CERN in November , a large number of data samples of B c meson have been collected and some hadronic B c decay modes have been measured by the LHC experiments. In view of the special and important roles of B c meson decays playing in the heavy flavor sector, we here give a short review on the status of two body.

    Decays of bottom mesons emitting tensor mesons in the final state using the Isgur-Scora-Grinstein-Wise II model. Two-body weak decay modes of the B+c meson leading to PP, VP, and VV states, where P and V represent the pseudoscalar meson and vector meson, respectively, are analyzed in .

Hadronic two body decays of bottom mesons to a single charmed meson plus a "light" pseudoscalar, vector or axial-vector meson are fully reconstructed using data collected with the CLEO II detector at the CESR e ^+e^- storage ring.

The data sample used consists of fb^{-1} on and fb^{-1} just below B| B threshold. Branching ratios and final state polarizations are measured for three Author: Jorge Luis Rodriguez. In this paper, we investigate phenomenologically two-body weak decays of the bottom mesons emitting pseudoscalar/vector meson and a tensor meson.

Form factors are obtained using the improved ISGW II model. Consequently, branching ratios for the. Abstract. We study exclusive nonleptonic two-body B c → (D (s), η c, B (s)) + F decays with F (pseudoscalar or vector meson) factored out in the QCD factorization approach.

The nonleptonic decay amplitudes are related to the product of meson decay constants and the form factors for semileptonic B c decays. As inputs in obtaining the branching ratios for a large set of nonleptonic B c decays Author: Ho-Meoyng Choi, Chueng-Ryong Ji.

Abstract. We present a study of three B 0 decay modes useful for time-dependent CP asymmetry measurements. From a sample of ×10 6 BB̄ meson pairs collected with the CLEO detector, we have reconstructed B >J/ψK 0 S, B >χ c1 K 0 S, and B >J/ψπ 0 decays.

The latter two decay modes have been observed for the first time. We describe a K 0 S-->π 0 π 0 detection Cited by: 3.

Title: Rare two-body decays of the top quark into a bottom meson plus an up or charm quarkAuthor: David d'Enterria, Hua-Sheng Shao. 1. Introduction. The phenomenological analyses of the bottom (B) meson decays provide exciting opportunities to test several models and the approaches within and beyond the Standard Model (SM).The understanding of B physics serves as a tool to study the interplay of strong and weak interaction dynamics in the SM and also a test of the new physics beyond the SM.

Abstract. We study exclusive nonleptonic two-body B c →(D (s),η c,B (s))+F decays with F (pseudoscalar or vector mesons) factored out in the QCD factorization nonleptonic decay amplitudes are related to the product of meson decay constants and the form factors for semileptonic B c decays.

As inputs in obtaining the branching ratios for a large set of nonleptonic B c decays, we. contributions for the charm baryon decays in our earlier work [16], we would like to present this work a systematic study of exclusive two body decays of bottom baryons.

The modes Λ b →Λ c P (V)are considered in the framework of soft-meson techniques with the inclusion of factorizable terms. Form factors of HQET are employed.

We find. The energetic exclusive two-body nonleptonic decays of B mesons are investigated in the relativistic independent quark model based on the confining potential in scalar-vector harmonic form within the factorization approximation.

The branching ratios for B decays to PP and PV channels with at least one charm meson in the final states are calculated from Lorentz invariant form factors and meson. I review the perturbative QCD approach to exclusive B meson decays, concentrating on the proof of the factorization theorem, the construction of the light-cone B meson wave function, the evaluation of heavy-to-light transition form factors, and the Sudakov effects in the end-point region of momentum fractions.

I also discuss the application of the perturbative QCD formalism to two-body. Rare two-body decays of the top quark into a bottom meson plus an up or charm quark David d'Enterria Hua-Sheng Shao 1 Détails 1 LPTHE - Laboratoire de Physique Théorique et Hautes Energies.

We have investigated exclusive two body decays of B-meson using model independent quark diagram scheme. We have shown that the recent measurement of the two body exclusive decays of B-mesons can allow us to determine the magnitude and even sign of the QD amplitude for B→VV decays.

Therefore, we become. Unlike the lower massed K and D mesons, B mesons can decay weakly into baryons. Using the SU(3) flavor symmetry of the strong interactions relations are derived between the rates for exclusive two-body B meson decays that produce low-lying charmed baryons.

Two-body weak decays of heavy mesons are studied using a simple non-relativistic model for the meson-quark-antiquark vertex. Numerical results are compared with experimental data where possible.

The properties of the amplitudes calculated suggest that dynamical factors are important in determining the nature of these decays. In the framework of QCD factorization, we study the B-meson exclusive decays B→χ cJ K where the spin-triplet P-wave charmonium states χ cJ (J=0,1,2) are described by the color-singlet nonrelativistic wave functions.

We find that for these decays (except χ c1) there are infrared divergences arising from nonfactorizable vertex corrections as well as logarithmic end-point singularities.

Two-body decays of Bs mesons Bijnens, J. LU and Hoogeveen, F. () In Physics Letters B (). p Mark; Abstract. We have calculated the decay rates of the B s meson in a number of exclusive two-body decay channels using the Bauer-Stech-Wirbel model for current matrix elements. The influence of the free parameters of the model on the predictions is studied.

Exclusive nonleptonic decays of bottom and charm baryons are studied within a relativistic three-quark model with a Gaussian shape for the momentum dependence of the baryon-three-quark vertex.

We include factorizing as well as nonfactorizing contributions to the decay amplitudes. We discuss a novel pertubative QCD approach on the exclusive non-leptonic two body B-meson decays. We briefly review its ingredients and some important theoretical issues on the factorization approaches.

We show numerical results which is compatible with recent experimental data for the charmless B-meson decays. The quasi-two-body decays B → K ρ → K π π can be also analyzed in an alternative approach based on two-body decays: the quark pair q q ¯ from a hard decay kernel forms the ρ meson, followed by its BW propagator, and then by the ρ → π π transition with the strength g ρ π π.

For the cases of three-body decays, however, the previous PQCD approach [42, 43] should be modified by introducing the two-meson distribution amplitudes [44][45][46][47] to describe the selected.Within the factorization-assisted topological-amplitude approach, we study the two-body charmed B meson decays Bu,d,s→D(*)M, with M denoting a light pseudoscalar (or vector) meson.

The meson decay constants and transition form factors are factorized out from the hadronic matrix element of topological diagrams.This paper presents the two body weak nonleptonic decays of B-mesons emitting vector (V) and vector (V) mesons within the framework of the diagrammatic approaches at flavor SU(3) symmetry.
