Heavy Quarkonium Spectrum and Production/Annihilation Rates to order
A. A. Penin, V. A. Smirnov, M. Steinhauser
We compute the third-order corrections to the heavy quarkonium spectrum and production/annihilation rates due to the leading renormalization group running of the static potential.…

Two-Loop Static QCD Potential for General Colour State
B. A. Kniehl, A. A. Penin, Y. Schröder +2
In this letter, we extend the known results for the QCD potential between a static quark and its antiquark by computing the two-loop corrections to the colour-octet state.
