Table 1: Selected calculations for reduced charm cross sections in DIS from different theory groups as used in this review. However, the tools that are available for O(α2s) fixed-order calculations of the heavy-quark production cross sections in ep collisions, which are mostly used for exclusive final states, do not comprise a The large charmand beauty-quark masses result in kinematical suppression of their production compared to the light-flavour cross sections. + With the applied track minimal transverse momentum cut of 0.5 GeV one obtains a good acceptance for low heavy-quark momenta, which is of high importance for measuring the charm and Double-differential cross-section measurements as a function of the D∗ transverse momentum and pseudorapidity have been performed by ZEUS in [171] and also in a previous charm milestone paper [168]	./cache/work_wlwbqlbfizasrpcccx4et6zjni.pdf	./txt/work_wlwbqlbfizasrpcccx4et6zjni.txt
