Description

We present exact results for the heavy-quark structure functions in deep-inelastic scattering (DIS) in different kinematical regimes and to next-to-next-to-leading order (NNLO) in perturbative QCD. We combine the behavior near threshold, in the high-energy limit and at asymptotically large $Q2 \gg m2$ to derive approximate expressions at NNLO accuracy. The remaining theoretical uncertainties of this approximation are negligible except in a region of small-$x$ and low $Q2$ and we illustrate the improvement in precision predictions for heavy-quark DIS.
