The production process N+N→N+N+nπ is investigated on the basis of covariant field theory. The production amplitude as well as elastic one is calculated under the special assumption about production mechanism. The eikonal approximation for nucleon trajectories is introduced, so these amplitudes are expressed in an impact parameter representation. They satisfy the s-channel unitarity for the elastic process. The Feynman scaling behavior for the pion inclusive spectra is reduced as an automatic consequence of the present model. Furthermore, the difference between the transverse and longitudinal distribution of pion momenta can be explained. The imaginary part of the phase shift in an elastic channel is reduced as a reflection of the production process, and it reproduces diffractive properties for the elastic differential cross section. Comparisons with p-p scattering data are made for various physical observables, namely, inclusive spectra for pions, average multiplicity, elastic and production cross sections and elastic differential cross section. Agreement is fairly satisfactory.
