Effects of the Hadronic Structure of the Photon at the DESYepCollider HERA

We investigate the production of hadronic jets with high transverse momenta $p_T$ at the forthcoming DESY $\mathrm{ep}$ collider HERA. We find that events where the exchanged quasireal photon is resolved into quarks and gluons dominate the two-jet cross section for $p_T\lesssim 40$ GeV. We also find that this class of events contributes about 20% to the total $b\overline{b}$ and $c\overline{c}$ production. The possibility to use these processes to measure the gluon content of the photon is discussed.
