In oder to study proton-proton bremsstrahlung moving towards the elastic limit, a detection system, consisting of Plastic-ball and SALAD, was set up and an experiment at 190 MeV incident beam energy was performed. Here, the experimental setup and the

The external-field QCD Sum Rules method is used to evaluate the coupling constants of the light-isoscalar scalar meson (``\sigma'' or \epsilon) to the \Lambda, \Sigma, and \Xi baryons. It is shown that these coupling constants as calculated from QCD

Nucleon-nucleon bremsstrahlung
Autor: Scholten, O., KalantarNayestanaki, N, Timmermans, RGE, Bakker, BLG
Publikováno v: Few-Body Problems in Physics, 768, 115-119
The present status of the theory for nucleon-nucleon bremsstrahlung is outlined. Microscopic calculations are compared with the experimental data for selected kinematics of the 190 MeV KVI pp gamma experiment. Large discrepancies between theory and e

STARTPAGE=297;ENDPAGE=299;TITLE=Few-Body Problems in Physics
The QCD Sum Rules method which links the hadronic degrees of freedom with the underlying QCD parameters, serves as a very useful tool to extract qualitative and quantitative information about hadron properties. The QCD sum rules method has been exten

K-Λ and K-Σ photo-production in a coupled channels framework

STARTPAGE=307;ENDPAGE=307;TITLE=Few-Body Problems in Physics
A coupled channels analysis, based on the K-matrix approach, is presented for photo-induced kaon production. It is shown that channel coupling effects are large and should not be ignored. The importance of contact terms in the analysis, associated wi

With the combined setup of the Crystal Barrel and TAPS photonspectrometers at ELSA in Bonn we have studied photonuclear reactions on protons and deuterons. From the series of experiments on single and multiple neutral meson emission we concentrate he

P- and T-odd two-nucleon interaction and the deuteron electric dipole moment
Autor: Liu, CP, Timmermans, RGE
Publikováno v: Physical Review C, 70(5):055501. AMER PHYSICAL SOC
The nuclear physics relevant to the electric dipole moment (EDM) of the deuteron is addressed. The general operator structure of the P- and T-odd nucleon-nucleon interaction is discussed and applied to the two-body contributions of the deuteron EDM,
