Fermionic corrections to quark and gluon form factors in four-loop QCD
Roman N. Lee, Andreas von Manteuffel, Robert M. Schabinger +3
We analytically compute all four-loop QCD corrections to the photon-quark and Higgs-gluon form factors involving a closed massless fermion loop. Our calculation of non-planar verte…
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.
Spin Dependence of Heavy Quarkonium Production and Annihilation Rates: Complete Next-to-Next-to-Leading Logarithmic result
A. A. Penin, A. Pineda, V. A. Smirnov +1
The ratio of the photon mediated production or annihilation rates of spin triplet and spin singlet heavy quarkonium states is computed to the next-to-next-to-leading logarithmic ac…
Potential NRQCD and Heavy-Quarkonium Spectrum at Next-to-Next-to-Next-to-Leading Order
B. A. Kniehl, A. A. Penin, V. A. Smirnov +1
The next-to-next-to-next-to-leading order (N^3LO) Hamiltonian of potential nonrelativistic QCD is derived. The complete matching of the Hamiltonian and the contribution from the ul…
Next-to-Next-to-Leading Logarithms in Four-Fermion Electroweak Processes at High Energy
J. H. Kühn, S. Moch, A. A. Penin +1
We sum up the next-to-next-to-leading logarithmic virtual electroweak corrections to the high energy asymptotics of the neutral current four-fermion processes for light fermions to…
