Heavy Quark Production in γγ Collisions

New results on inclusive heavy quark production in gamma gamma collisions are presented. Charm and bottom production are investigated at LEP II energies by the experiments ALEPH, DELPHI, L3, and OPAL. The total and differential cross sections for charm quarks are measured. The contributions from the direct and single-resolved processes are separated and their fractions quantified. More detailed studies, such as the dependence of the cross section on the two-photon centre-of-mass energy and the charm structure function F^2_gamma,c, are reported. The inclusive bottom cross section is presented. Measurements are compared to next-to-leading order calculations.
