Analysis of experimental data on inclusive production of rho/sup 0/ and. omega. mesons in the framework of certain theoretical models

Experimental data on the inclusive production of rho/sup 0/ and ..omega.. mesons obtained in the Sigma apparatus are analyzed in the framework of the quark-fusion model and the one-pion-exchange model. Parametrizations of the structure functions of the proton and pion are obtained. It is shown that the shape of the t distribution of the cross section for inclusive production of rho/sup 0/ mesons by pions in the region x> or =0.9 and small values of Vertical BartVertical Bar is satisfactorily described in the framework of the one-pion-exchange model. The ratio of the decay probabilities B/sub omegaarrow-rightmumu//B/sub rhoarrow-rightmumu/ is estimated to be 1.4 +- 0.6.
