Abstract
The double-differential inclusive di-jet cross section in photoproduct ion processes is measured with the H1 detector at HERA. The cross sect ion is determined as a function of the average transverse jet energy E -T(jets) for ranges of the fractional energy x(gamma)(jets) of the par ton from the photon side. An effective leading order parton distributi on in the photon is determined at large parton fractional energies for scales between 80 < p(T)(2) < 1250 GeV2. The measurement is compatibl e with the logarithmic scale dependence that is predicted by perturbat ive QCD.
