Abstrakt: Inclusive production of ϕ,K*0, and $$\overline {K*^0 } $$ mesons has been measured in γp, π±p andK± p collisions at beam energies of 65 GeVγ<175 GeV andEπ/K =80 and 140 GeV. Cross sections have been determined over the range 0F<1.0 and 0T<1.8 GeV/c. Emphasis is put on the comparison of cross sections for different projectiles as a function ofxF so as to study the effects of common quarks between the beam particle and the detected ϕ,K*0 or $$\overline {K*^0 } $$ . The data are compared with a parton fusion model. Many features of the data are well explained. In detail the strange quark appears to carry a large fraction of the kaon momentum and the contribution of the valence quarks from the proton is small.
