abstract
We make up-to-date QCD predictions for open charm and bottom production at RHIC in nucleon-nucleon collisions at \sqrt{S} = 200 GeV. We also calculate the electron spectrum resulting from heavy flavor decays to allow direct comparison to the data. A rigorous benchmark, including the theoretical uncertainties, is established against which nuclear collision data can be compared to obtain evidence for nuclear effects.

In Cu+Au collisions, heavy-quark directed flow is an order of magnitude larger than charged-hadron flow and shows strong sensitivity to initial spatial distributions and temperature-dependent drag.
