The gradient flow at higher orders in perturbation theory
Abstract
Various results for higherorder perturbative calculations in the gradientflow formalism are reviewed, including the gradientflow beta function and the smallflowtime expansion of the hadronic vacuum polarization and the energymomentum tensor. In addition, the strategy of regions is outlined in order to obtain systematic expansions of gradientflow integrals, for example at large and small flow times.
