Charmed hadrons are identified by electrons and muons from semileptonic decays. The direct process <math><mtext>γγ→c</mtext><mtext>c</mtext><mtext>̄</mtext></math> is found to be insufficient to describe the data. The measured cross section values and event distributions require contributions from resolved processes, which are sensitive to the gluon density in the photon. |
