Abstract
Measurements are reported of inclusivef 2(1270) andf 0(975) production in γp, π± p andK ± p collisions at photon beam energies of 65 to 175 GeV and hadron beam energies of 80 and 140 GeV. Thef 2 andf 0 mesons were found at masses of 1.250 GeV and 0.961 GeV respectively. Inclusivef 2 production at lowx F was found to have a similarp T dependence for each beam type, whereas an additional pion-exchange contribution was found for production by pions at highx F. Cross sections are compared with those for ρ0 production and give no indication of a non-q\(\bar q\) component in eitherf-meson state.
