HEAVY-FLAVOR PHOTO- AND ELECTROPRODUCTION AT NLO

We review one-particle inclusive production of heavy-flavored hadrons in a framework which resums the large collinear logarithms through the evolution of the FFs and PDFs and, at the same time, retains the full dependence on the heavy-quark mass without additional theoretical assumptions. The main focus is on the production of D* mesons in deep inelastic electron–proton scattering at HERA. We show results, neglecting for the time being the heavy-quark mass terms, for deep inelastic D* meson production at finite transverse momenta. Work to implement this process in the above mentioned massive QCD framework is in progress.
