Heavy-Meson Bag Parameters using Gradient Flow
Matthew Black, Robert V. Harlander, Jonas T. Kohnen +4
We demonstrate the use of the gradient flow combined with the short flow-time expansion (GF+SFTX) as a renormalization procedure for four-quark operator matrix elements and associa…
A new approach to quark mass determination using the gradient flow
Hiromasa Takaura, Robert V. Harlander, Fabian Lange
We propose a new method to determine quark masses using ratios of the vacuum-expectation values (VEVs) of flowed quark bilinear operators. They can be expressed as functions of the…
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…
Gradient Flow Renormalisation for Meson Mixing and Lifetimes
Matthew Black, Robert Harlander, Fabian Lange +3
Fermionic gradient flow in combination with the short-flow-time expansion provides a computational method where the renormalisation of hadronic matrix elements on the lattice can b…
Short-flow-time expansion of quark bilinears through next-to-next-to-leading order QCD
Janosch Borgulat, Robert V. Harlander, Jonas T. Kohnen +1
The gradient-flow formalism proves to be a useful tool in lattice calculations of quantum chromodynamics. For example, it can be used as a scheme to renormalize composite operators…
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…
