Four-loop moments of the heavy quark vacuum polarization function in perturbative QCD
K. G. Chetyrkin, J. H. Kühn, C. Sturm
New results at four-loop order in perturbative QCD for the first two Taylor coefficients of the heavy quark vacuum polarization function are presented. They can be used to perform…

Electroweak corrections to hadronic photon production at large transverse momenta
Johann H. Kuhn, A. Kulesza, S. Pozzorini +1
We study the impact of electroweak radiative corrections on direct production of photons with high transverse momenta at hadron colliders. Analytic results for the weak one-loop co…
