This document provides a comprehensive summary of the state-of-the-art, challenges, and
prospects in the experimental and theoretical study of the strong coupling $\alpha_s $. The …

Determination of by the non-perturbative decoupling method

M Dalla Brida, R Höllwieser, F Knechtli… - The European Physical …, 2022 - Springer
We present the details and first results of a new strategy for the determination of α s (m
Z)(ALPHA Collaboration et al. in Phys. Lett. B 807: 135571, 2020). By simultaneously …

The gradient flow coupling at high-energy and the scale of SU (3) Yang–Mills theory

M Dalla Brida, A Ramos - The European Physical Journal C, 2019 - Springer
Using finite size scaling techniques and a renormalization scheme based on the Gradient
Flow, we determine non-perturbatively the β β-function of the SU (3) Yang–Mills theory for a …

Non-perturbative quark mass renormalisation and running in QCD

I Campos, P Fritzsch, C Pena, D Preti, A Ramos… - The European Physical …, 2018 - Springer
We determine from first principles the quark mass anomalous dimension in N_\scriptstyle f=
3 N f= 3 QCD between the electroweak and hadronic scales. This allows for a fully non …

Past, present, and future of precision determinations of the QCD coupling from lattice QCD

M Dalla Brida - The European Physical Journal A, 2021 - Springer
Non-perturbative scale-dependent renormalization problems are ubiquitous in lattice QCD
as they enter many relevant phenomenological applications. They require solving non …

[HTML][HTML] The quark-mass dependence of the potential energy between static colour sources in the QCD vacuum with light and strange quarks

J Bulava, F Knechtli, V Koch, C Morningstar… - Physics Letters B, 2024 - Elsevier
The low-lying energy spectrum of the static-colour-source-anti-source system in a vacuum
containing light and strange quarks is computed using lattice QCD for a range of different …

Light quark masses in lattice QCD with Wilson fermions: ALPHA Collaboration

M Bruno, I Campos, P Fritzsch, J Koponen… - The European Physical …, 2020 - Springer
We present a lattice QCD determination of light quark masses with three sea-quark flavours
(N_ f= 2+ 1 N f= 2+ 1). Bare quark masses are known from PCAC relations in the framework …

Scale setting for QCD: Alpha Collaboration

R Höllwieser, F Knechtli, T Korzec - The European Physical Journal C, 2020 - Springer
We present the scale setting for a new set of gauge configurations generated with N_ f= 3+ 1
N f= 3+ 1 Wilson quarks with a non-perturbatively determined clover coefficient in a massive …

[HTML][HTML] How perturbative are heavy sea quarks?

A Athenodorou, J Finkenrath, F Knechtli, T Korzec… - Nuclear Physics B, 2019 - Elsevier
Abstract Effects of heavy sea quarks on the low energy physics are described by an effective
theory where the expansion parameter is the inverse quark mass, 1/M. At leading order in …
