An explicit Mueller-Regge model (with poles only) is constructed for the investigation of single-particle-inclusive processes in the quasi-two-body and triple-Regge subspace of the fragmentation region. The model is then applied in studies of nucleon production processes. The inclusive cross sections are considered and compared with the available data. The qualitative agreement between the cross section data and the model is reasonable, but the model is not satisfactory in details. Regge cuts are introduced into the model via the absorption model prescription. Then nucleon production processes are reinvestigated in this modified model and the polarization of the produced nucleon is predicted. The model is applied to Lambda production (in a nucleon interaction), and the agreement between theoretical prediction and the experimental data for the polarization of the Lambda in the small p region is remarkable. Finally, the model is applied to tensor meson production and the cross section and the spin density matrix elements are predicted.
