Polarization phenomena in the reaction NN to NNpi near threshold
C. Hanhart, J. Haidenbauer, O. Krehl +1
First calculations for spin-dependent observables of the reactions , and near threshold are presented, employing the Jülich model for pio…
The piNN vertex function in a meson-theoretical model
R. Boeckmann, C. Hanhart, O. Krehl +2
The piNN vertex function is calculated within a dispersion theoretical approach, including both pi-rho and pi-sigma intermediate states, where the sigma meson is an abbreviation fo…
Enhancement of Threshold Cross Sections by In-Medium Final State Interactions
R. Rapp, J. W. Durso, Z. Aouissat +5
We address the problem of pion production in low energy -nucleus collisions. For the production mechanism we assume a simple model consisting of a coherent sum of single pion ex…
Role of the isobar in the reaction near threshold
C. Hanhart, J. Haidenbauer, O. Krehl +1
A model calculation for pion production in nucleon-nucleon collisions is presented. Direct production, pion rescattering and contributions from pair diagrams are taken into account…
Radiative corrections to the background of decay
A. B. Arbuzov, O. Krehl, E. A. Kuraev +2
Radiative muon decay in the kinematics similar to the neutrinoless decay is considered. Radiative corrections due to 1-loop virtual photons and emission of additional sof…
Working group on and N interactions - Summary
Ulf-G. Meißner, Martin Sevior, A. Badertscher +16
This is the summary of the working group on and N interactions of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. Each talk is represented by an extended one pa…
