Anatomy of three-body decay I. Schematic models
Sequential three-body decay proceeds via spatially confined quasi-stationary twobody configurations. Direct three-body decay populates the three-body continuum without intermediate steps. The relative importance of these decay modes is discussed in a schematic model employing only Coulomb or centrifugal barrier potentials. Decisive dimensionless charge, mass and energy ratios are derived. Seque...
متن کاملAnatomy of three-body decay III. Energy distributions
We address the problem of calculating momentum distributions of particles emerging from the three-body decay of a many-body resonance. We show that these distributions are determined by the asymptotics of the coordinate-space complexenergy wave-function of the resonance. We use the hyperspherical adiabatic expansion method where all lengths are proportional to the hyperradius. The structures of...
متن کاملAnatomy of three-body decay II. Decay mechanism and resonance structure
We use the hyperspherical adiabatic expansion method to discuss the the two mechanisms of sequential and direct three-body decay. Both short-range and Coulomb interactions are included. Resonances are assumed initially populated by a process independent of the subsequent decay. The lowest adiabatic potentials describe the resonances rather accurately at distances smaller than the outer turning ...

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...
