چکیده

We present theoretical and experimental considerations pertaining to deeply inelastic heavyflavour production at HERA. The various theoretical uncertainties in the cross section calculation are discussed. Cuts are imposed to determine the fraction of charm production accessible to the detectors. The production of charm at asymptotic Q and bottom production are also covered. Experimental aspects include current charm production data analysis and prospects for future analyses including anticipated high precision and distinguishing photon-gluon fusion charm events from excitation from the charm parton density. The feasibility of measuring F bb 2 (x,Q ) is investigated. To appear in abbreviated form in the proceedings of the workshop “Future Physics at HERA”, DESY, Hamburg, 1996.

Constraining the Proton ’ s Gluon Density

We analyze the capability of charm production in deep-inelastic ep scattering at HERA to constrain the gluon distribution g(y, µ 2) of the proton. The dependence of the theoretical predictions for the charm structure function F c 2 on the mass factorization scale µ and the charm mass is investigated. We demonstrate that F c 2 is well suited for a rather clean and local gluon measurement at smal...
