摘要：I discuss the current status of the comparison between theoretical predictions
and experimental data, relevant to the production of open charm and bottom quarks
in photon-hadron and photon-photon collisions. I advocate the use of a formalism that
matches xed-order computations to resummed computations in order to make rm statements
on heavy flavour production as described by perturbative QCD.
