Abstract
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 GeV<E γ<175 GeV andE π/K =80 and 140 GeV. Cross sections have been determined over the range 0<x F<1.0 and 0< PT<1.8 GeV/c. Emphasis is put on the comparison of cross sections for different projectiles as a function ofx F 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.
