Various results for higher-order perturbative calculations in the gradient-flow formalism are reviewed, including the gradient-flow beta function and the small-flow-time expansion of the hadronic vacuum polarization and the energy-momentum tensor. In addition, the strategy of regions is outlined in order to obtain systematic expansions of gradient-flow integrals, for example at large and small flow times.ย

Nonperturbative Decoupling of Massive Fermions

SU(2) gauge theory with N f = 24 massless fermions is non-interacting at long distances, i.e. it has an infrared ๏ฌxed point at vanishing coupling. With massive fermions the fermions are expected toโ€ฆ
