Abstract: Open heavy flavour production at e + e − colliders in deeply inelastic eγ scattering has an interesting feature: the structure function F 2 ( x , Q 2 ) for this process is calculable for x > 0.01, and is essentially proportional to the gluon density in the photon for smaller x values. We give estimates for event rates at LEP2 and a Next Linear Collider in x , Q 2 bins, and present differential distributions in the transverse momentum and rapidity of the heavy quark for the case of charm. We include all next-to-leading-order QCD corrections, and find theoretical uncertainties are well under control.
