1. Strong Running Coupling from the Gauge Sector of Domain Wall Lattice QCD with Physical Quark Masses / Zafeiropoulos, S. ; Boucaud, Ph. ; De Soto, F. ; Rodríguez-Quintero, J. ; et al
We report on the first computation of the strong running coupling at the physical point (physical pion mass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of domain wall fermions. [...]

2. Discretization effects on renormalized gauge-field Green’s functions, scale setting, and the gluon mass / Boucaud, Ph. ; De Soto, F. ; Raya, K. ; Rodríguez-Quintero, J. ; et al
The SU(3) gauge-field propagators computed from the lattice have been exhaustively used in the investigation of the low-momentum dynamics of QCD, in a judicious interplay with results from other nonperturbative approaches, and for the extraction of fundamental parameters of QCD like ΛMS¯ as well. [...]

3. Instanton liquid properties from lattice QCD / Athenodorou, A. ; Boucaud, Ph. ; Soto, F. ; Rodríguez-Quintero, J. ; et al
We examined the instanton contribution to the QCD configurations generated from lattice QCD for N F = 0, N F = 2 + 1 and N F = 2 + 1 + 1 dynamical quark flavors from two different and complementary approaches. [...]

4. On the zero crossing of the three-gluon vertex / Athenodorou, A. ; Binosi, D. ; Boucaud, Ph. ; De Soto, F. ; et al
We report on new results on the infrared behavior of the three-gluon vertex in quenched Quantum Chromodynamics, obtained from large-volume lattice simulations. [...]

5. Gluon Green functions free of quantum fluctuations / Athenodorou, A. ; Boucaud, Ph. ; De Soto, F. ; Rodríguez-Quintero, J. ; et al
This letter reports on how the Wilson flow technique can efficaciously kill the short-distance quantum fluctuations of 2- and 3-gluon Green functions, remove the ΛQCD scale and destroy the transition from the confining non-perturbative to the asymptotically-free perturbative sector. [...]

6. Three-gluon running coupling from lattice QCD at N f = 2 + 1 + 1: a consistency check of the OPE approach / Ph. Boucaud ; M. Brinet ; F. De Soto ; V. Morenas ; et al
We present a lattice calculation of the renormalized running coupling constant in symmetric (MOM) and asymmetric $ \left( {\widetilde{\mathrm{MOM}}} \right) $ momentum substraction schemes including u , d , s and c quarks in the sea. [...]
