 +====== TTP09-05 Quark and gluon form factors to three loops ====== 
 +   <hidden TTP09-05  Quark and gluon form factors to three loops > We compute the form factors of the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons to three-loop order within massless perturbative Quantum Chromodynamics. These results provide building blocks for many third-order cross sections. Furthermore, this is the first calculation of complete three-loop vertex corrections.
