Query: Heavy-quark correlations in deep-inelastic electroproduction   We have completed the next-to-leading order perturbative QCD corrections to
the virtual-photon exclusive differential cross sections for heavy quark
production in deep-inelastic electron-proton scattering, i.e. $e + P
\rightarrow Q + \overline{Q} + X$. Using these results, we have computed
distributions which are sensitive to correlations among the heavy quark, the
heavy antiquark, and the associated jet. Some predictions for charm and bottom
heavy quark production at the electron-proton collider HERA are presented.
