Abstract
Using some of the existing models for multiple production of hadrons we have computed here theoretically the inelasticity partial coefficients in proton-iron collisions at very high energies ( ≈ 0.5 TeV) and have compared our estimated values with the very recent measurements of Avakian et al. Calculations are intended to be done mostly for the central region (x ≈ 0) for which Wong's model, although considered here, is not very suitable which explains its lack of satisfactory agreement with the data. So far as this parameter is concerned, barring QCD, all other models stand comparably quite well. The experimental data on the same parameter for pion-iron collisions too have also been analysed with the help of only a single model (SCM) and there is also a fair agreement between this model and the measurements. The lack of good agreement of the QCD model with the data is also quite easily explainable.
