The light-fermion contribution to the exact Higgs-gluon form factor in QCD
Abstract An analytical expression for the three-loop form factors for ggH and γγH is derived for the contributions which involve massless quark loops. The result is expressed in terms of harmonic polylogarithms. It fully agrees with previously obtained kinematical expansions, and confirms a recent s...
