Description
In my talk, I will report on the recent four-loop calculation of the small cusp angle expansion of the cusp anomalous dimension in QCD and the heavy quark field anomalous dimension in HQET. Also, I will provide details on the calculation of four-loop integrals containing eikonal propagators with the method of difference equations in the space-time dimension.
