Inclusive charm production in two-photon collisions at LEP
Abstract
The cross section of charm production in γγ collisions σ(e+e−→e+e−cc̄X) is measured at LEP with the L3 detector at centre-of-mass energies from 91 GeV to 183 GeV. Charmed hadrons are identified by electrons and muons from semileptonic decays. The direct process γγ→cc̄ 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 …
