Matter dependence of the four-loop cusp anomalous dimension

21 Jun 2019 Henn Johannes M. Peraro Tiziano Stahlhofen Maximilian Wasser Pascal

We compute analytically the matter-dependent contributions to the quartic Casimir term of the four-loop light-like cusp anomalous dimension in QCD, with $n_f$ fermion and $n_s$ scalar flavours. The result is extracted from the double pole of a scalar form factor... (read more)
