Relativistic and polarization phenomena in NN → dπ processes

A detailed analysis of processes of the type NN → dπ is 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. Some of these polarization characteristics can change the sign by including these effects. The influence of the inclusion of a P-wave in the deuteron wave function is studied, too. The comparison of the calculation results of all the observables with the experimental data on the reaction pp → dπ+ is presented
