The differential cross section, dσ/dt for ω meson exclusive photoproduction on the proton above the resonance region (2.6<W<2.9 GeV) was measured up to a momentum transfer −t=5

using the CLAS detector at Jefferson Laboratory. The
ω
channel was identified by detecting a proton and
π+
in the final state and using the missing mass technique. While the low momentum transfer region shows the typical diffractive pattern expected from Pomeron and Reggeon exchange, at large
−t
the differential cross section has a flat behavior. This feature can be explained by introducing quark interchange processes in addition to the QCD-inspired two-gluon exchange.
