AbstractAbstract
[en] Data for D*±(2010) meson electroproduction in the range 10< Q2<1350 GeV2 has recently been presented by the ZEUS collaboration at HERA. We use these results together with previously published data for Q2>1 GeV2 to test whether one can distinguish between different theoretical schemes for charm quark electroproduction. We find that up to the largest Q2 measured, it is not possible to make such a differentiation. Then we point out the regions where differences between the various schemes arise. (orig.)
