ResumoThe inclusive production of D∗± mesons in single tagged photon-photon collisions is investigated using the JADE detector at PETRA. D∗± mesons are reconstructed through their decay into D0+π± where the D0 decays via D0→Kππ0. The event rate and topology are compared to the expectations of c quark production in the quark-parton model: γγ→cc.
