Computation of form factors in massless QCD with finite master integrals

Computation of form factors in massless QCD with finite master integrals

We present the bare one-, two-, and three-loop form factors in massless quantum chromodynamics as linear combinations of finite master integrals. Using symbolic integration, we compute their ε expansions and thereby reproduce all known results with an independent method. Remarkably, in our finite b...
