Abstract
We present the first genuine QCD five-loop calculation of the vacuum polarization functions: analytical terms of order to the absorptive parts of vector and scalar correlators. These corrections form an important gauge-invariant subset of the full correction to annihilation into hadrons and the Higgs decay rate into hadrons, respectively. They discriminate between different widely used estimates of the full result.
