Massive three-loop form factors: anomaly contribution

We compute three-loop corrections to the singlet form factors for massive quarks using a semianalytic method which provides precise results over the whole kinematic range. Particular emphasis is put on the anomaly contribution originating from an external axial-vector current. We also discuss in det...
