Exact quark-mass dependence of the Higgs-photon form factor at three loops in QCD

Exact quark-mass dependence of the Higgs-photon form factor at three loops in QCD

Abstract We follow up on our discussion of the exact quark-mass dependence of the Higgs-gluon form factor at three loops in QCD [1] and turn our attention to the closely related Higgs-photon form factor. Similarly to our previous work, we intend to examine the form factor for the decay of a Higgs-bo...
