Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملCharmless Exclusive Baryonic B Decays
We present a systematical study of two-body and three-body charmless baryonic B decays. Branching ratios for two-body modes are in general very small, typically less than 10−6, except for the decays with a ∆ resonance in the final state. For example, the branching ratio of the tree-dominated decay B− → p∆̄−− can be as large as 6× 10−6, and the penguin-dominated decay B− → Σ+∆̄−− is at the level o...
متن کاملNonresonant Three-body Decays of D and B Mesons
Nonresonant three-body decays of D and B mesons are studied. It is pointed out that if heavy meson chiral perturbation theory (HMChPT) is applied to the heavy-light strong and weak vertices and assumed to be valid over the whole kinematic region, then the predicted decay rates for nonresonant charmless 3-body B decays will be too large and especially B− → π−K+K− greatly exceeds the current expe...
متن کاملThree-body decay of the d dibaryon
Under certain circumstances, a three-body decay width can be approximated by an integral involving a product of two off-shell two-body decay widths. This “angle-average” approximation is used to calculate the πNN decay width of the d(J = 3, T = 0) dibaryon in a simple ∆ model for the most important Feynman diagrams describing pion emissions with baryon-baryon recoil and meson retardation. The d...
متن کاملR-matrix and dynamical model calculations of three-body resonance decay widths
Calculations of the decay widths of three-body resonances are considered using both R-matrix and dynamical three-body theoretical models. The R-matrix approach, which treats the three-body decay as two, ordered two-body decays, has both simultaneous and sequential particle emission pathways, each with an associated decay width. The question of how these two widths should be combined to determin...
متن کاملStatus of baryonic B decays
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 frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process b → sγ are discussed. Apart from the first observation of the radiative penguin decay B− →...
