Abstract

Inclusive production of phi, K*0, and K*0BAR mesons has been measured in gammap, pi+/-p and K+/-p collisions at beam energies of 65 GeV <E(gamma) <175 GeV and E(pi/K) = 80 and 140 GeV. Cross sections have been determined over the range 0 <x(F) <1.0 and 0 <p(t) <1.8 GeV/c. Emphasis is put on the comparison of cross sections for different projectiles as a function of x(F) so as to study the effects of common quarks between the beam particle and the detected phi, K*0 or K*0BAR. 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.
