چکیده

The effect of the nucleon recoil for antikaon-deuteron scattering is investigated in the framework of effective field theory. In particular, we concentrate on the calculation of the nucleon recoil effect for the double-scattering process. It is shown that the leading correction to the static term that emerges at order ξ with ξ = MK/mN vanishes due to a complete cancellation of individually large contributions. The resulting recoil effect in this process is found to be of order of 10-15% as compared to the static term. We also briefly discuss the application of the method in the calculations of the multiple-scattering diagrams. Pacs: 36.10.Gv, 13.75.Cs, 13.75.Jz

اندازه‌گیری مشاهده‌پذیرهای کانال تجزیه سه‌جسمی برای بخشی از فضای فاز پراکندگی دوترون- دوترون در انرژی برنوکلئون

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...

Tensor polarization in elastic electron-deuteron scattering in the momentum transfer range 3.8 <= Q <= 4.6 fm-1.

The tensor polarization of the recoil deuteron in elastic electron-deuteron scattering has been measured at the Bates Linear Accelerator Center at three values of four-momentum transfer, Q = 3.78, 4.22, and 4.62 fm-', corresponding to incident electron energies of 653, 755, and 853 MeV. The scattered electrons and the recoil deuterons were detected in coincidence. The recoil deuterons were tran...

The role of the nucleon recoil in low–energy meson–nucleus reactions

The role of the nucleon recoil corrections in low–energy meson–nucleus interactions is examined. We demonstrate explicitly when calculations within the static approximation are justified and when the recoil terms need to be kept explictly in the propagators, depending on whether the S-wave two–nucleon intermediate state is Pauli blocked or not, while the meson is in flight. While the effect is ...

Relativistic effect on low-energy nucleon-deuteron scattering.

The relativistic effect on differential cross sections, nucleon-to-nucleon and nucleonto-deuteron polarization transfer coefficients, and the spin correlation function, of nucleon-deuteron elastic scattering is investigated employing several three-dimensional relativistic three-body equations and several nucleon-nucleon potentials. The polarization transfer coefficients are found to be sensitiv...

Low Energy Proton-Deuteron Scattering with Exact Treatment of Coulomb Force

A modified version of the Faddeev three-body equation to accommodate the Coulomb interaction, which was used in the study of three-nucleon bound states, is applied to the proton-deuteron scattering problem at energies below the three-body breakup threshold. A formal derivation of the equation in a time-independent scattering theory is given. Numerical results for phase shift parameters are pres...
