New tests of quark-parton model

It is shown that a simple constraint between F/sup mun//sub 2//F/sup mup//sub 2/ and F/sup nup//sub 2//F/sup mup//sub 2/ derived from the basic properties of QCD that are contained in the quark-parton model is not satisfied by the present experimental data.

Zusammenfassung:	It is shown that a simple constraint between F/sup mun//sub 2//F/sup mup//sub 2/ and F/sup nup//sub 2//F/sup mup//sub 2/ derived from the basic properties of QCD that are contained in the quark-parton model is not satisfied by the present experimental data. The measurement of semi-inclusive cross sections that may clarify the issue on the d/u ratio is suggested.
