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…
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 $…
Gradient flow for parton distribution functions: first application to the pion
Anthony Francis, Patrick Fritzsch, Robert V. Harlander +9
Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operator…
Renormalized quark masses using gradient flow
Matthew Black, Robert V. Harlander, Anna Hasenfratz +2
We propose a new and simple method for determining the renormalized quark masses from lattice simulations. Renormalized quark masses are an important input to many phenomenological…
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…
