Abstract
Experimental studies of open charm production in two-photon processes have been performed. In the measurement, charmed hadrons were identifi ed by electrons from their semi-leptonic decays. The result was compar ed with calculations based on the direct process and photon-gluon fusi on process by resolved photons. We found that the effect of the gluon component in a photon is substantial in the observed events.
