It is suggested that the dominant contribution to the observed increase in the γp cross section of 2 to 6 μb over the expectations of vector-meson dominance arises from the production of high-transverse-momentum jets and not charm as has been widely interpreted. The cross section for the production of three jets, one along the collision axis and two with high pt, satisfactorily accounts for the deviation from ρ, ω, φ contributions. The charm component is found to be only a small fraction of the observed increase. © 1979 The American Physical Society.
