Abstract
Inclusive production of phi, K0, 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 bee n determined over the range 0 < x(F) < 1.0 and 0 < p(t) < 1.8 GeV/c. E mphasis is put on the comparison of cross sections for different proje ctiles as a function of x(F) so as to study the effects of common quar ks between the beam particle and the detected phi, K0 or K*0BAR. The data are compared with a parton fusion model. Many features of the dat a are well explained. In detail the strange quark appears to carry a l arge fraction of the kaon momentum and the contribution of the valence quarks from the proton is small.
