Relativistic NN scattering without partial wave decomposition
We consider the covariant Spectator equation with a One Boson Exchange (OBE) kernel, and apply it to the NN system. Relativistic effects such as retardation and negative-energy state components are included in that equation. We develop a method, based on the Padé method, to solve the Spectator equation without partial wave decomposition. The convergence of the partial wave decomposition series ...
متن کاملRelativistic NN scattering equations without partial-wave decomposition
Modern experimental facilities such as TJNAF and Julich are probing the baryonic structure and interactions at intermediate energies (∼ GeV), through electromagnetic and strong reactions involving high momentum transfer [1]. To describe the NN interaction in the intermediate energy range (∼ 300 MeV-1 GeV), particle production mechanisms have to be included. Relativistic effects became also impo...
متن کاملQuantum scattering problem without partial-wave analysis
We have suggested a method for treating different quantum few-body dynamics without usual partial-wave analysis. With this approach new results were obtained in the physics of ultracold atom-atom collisions and ionization and excitation/deexitation of helium ions. The developed computational scheme opens new possibilities for analysis the actual problem of ultracold atom wave-packets collisions...
متن کاملMulti-variate Bateman method for two-body scattering without partial-wave decomposition
The use of Batemanmethod for solving the two-variable version of the twobody Lippmann–Schwinger equation without recourse to partial-wave decomposition is investigated. Bateman method is based on a special kind of interpolation of the momentum representation of the potential on a multi-variate grid. A suitable scheme for the generation of a multi-variate Cartesian grid is described. The method ...
متن کاملRelativistic three-particle scattering equations.
We derive a set of relativistic three-particle scattering equations in the three-particle c.m. frame employing a relativistic three-particle propagator suggested long ago by Ahmadzadeh and Tjon in the c.m. frame of a two-particle subsystem. We make the coordinate transformation of this propagator from the c.m. frame of the two-particle subsystem to the three-particle c.m. frame. We also point o...
