The determination of potential scales in 2+1 flavor QCD
Tom Matty Bo Asmussen, Roman Höllwieser, Francesco Knechtli +1
We calculate the hadronic scales , and their ratio on flavor QCD ensembles generated by the CLS consortium. These scales are determined from a…

The strength of the interaction between quarks and gluons
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +4
Modern particle physics experiments, e.g. at the Large Hadron Collider (LHC) at CERN, crucially depend on the precise description of the scattering processes in terms of the known…

Hessian-free force-gradient integrators
Kevin Schäfers, Jacob Finkenrath, Michael Günther +1
We propose a new framework of Hessian-free force-gradient integrators that do not require the analytical expression of the force-gradient term based on the Hessian of the potential…
