The gradient-flow coupling of three-and four-dimensional QED
Lars Georg, Robert V. Harlander, Robert H. Mason
We evaluate the QED coupling in the gradient-flow scheme in three and four space-time dimensions. Our general result applies to any theory with a U(1) gauge field coupled to arbita…

Quark-mass effects in gradient-flow observables through next-to-next-to-leading order in QCD
Robert V. Harlander, Robert H. Mason
We provide results for the vacuum expectation values of the flowed action density, the quark condensate, and the quark kinetic operator in the gradient-flow formalism. We work in $…
