Relativistic Calculation of Polarization Observables in NN -> DπProcesses
A. Yu. Illarionov, G. I. Lykasov
Abstract
A detailed analysis of processes of the type NN -> dπis presented taking into account the exchange graphs of a nucleon and a pion. A large sensitivity of polarization observables to the off-mass shell effects of nucleons inside the deuteron is shown. The influence of the inclusion of the P-wave in the deuteron wave function (DWF) is studied. We have analyzed the sensitivity of all the observables to the form of πNN - current taking into account the off-shellnis of the nucleon and the choice of the DWF relativistic form. From the results one can see the very large sensitivity of all the observables, especially of the polarization characteristics to the choice of the DWF form.
