Determining the Quark Mass with the Gradient Flow

Hiromasa Takaura, Robert Harlander, Fabian Lange

We propose a new method to determine the quark mass by using bilinear operators of the flowed quark field defined within the gradient-flow formalism. This method enables the quark…

Towards the next Kira release

Fabian Lange, Johann Usovitsch, Zihao Wu

The reduction of Feynman integrals to a basis of master integrals plays a crucial role for many high-precision calculations and Kira is one of the leading tools for this task. In t…

Using Gradient Flow to Renormalise Matrix Elements for Meson Mixing and Lifetimes

Matthew Black, Robert Harlander, Fabian Lange +3

Neutral meson mixing and meson lifetimes are theory-side parametrised in terms four-quark operators which can be determined by calculating weak decay matrix elements using lattice…

Massive three-loop form factors: anomaly contribution

Matteo Fael, Fabian Lange, Kay Schönwald +1

We compute three-loop corrections to the singlet form factors for massive quarks using a semi-analytic method which provides precise results over the whole kinematic range. Particu…

Singlet and non-singlet three-loop massive form factors

Matteo Fael, Fabian Lange, Kay Schönwald +1

We consider Quantum Chromodynamics with external vector, axial-vector, scalar and pseudo-scalar currents and compute three-loop corrections to the corresponding vertex function tak…
