Chiral condensate in nf=2 QCD from the Banks-Casher relation
Georg P. Engel
Exploiting the Banks-Casher relation, we present a direct determination of the chiral condensate in two-flavor QCD, computing the mode number of the O(a)-improved Wilson-Dirac oper…
Spectral density of the Dirac operator in two-flavour QCD
Georg P. Engel, Leonardo Giusti, Stefano Lottini +1
We compute the spectral density of the (Hermitean) Dirac operator in Quantum Chromodynamics with two light degenerate quarks near the origin. We use CLS/ALPHA lattices generated wi…
Simulation of QCD with N_f=2+1 flavors of non-perturbatively improved Wilson fermions
Mattia Bruno, Dalibor Djukanovic, Georg P. Engel +11
We describe a new set of gauge configurations generated within the CLS effort. These ensembles have N_f=2+1 flavors of non-perturbatively improved Wilson fermions in the sea with t…
Testing the Witten-Veneziano mechanism with the Yang-Mills gradient flow on the lattice
Marco Cè, Cristian Consonni, Georg P. Engel +1
We present a precise computation of the topological charge distribution in the Yang-Mills theory. It is carried out on the lattice with high statistics Monte Carlo simulati…
Chiral symmetry breaking in QCD Lite
Georg P. Engel, Leonardo Giusti, Stefano Lottini +1
A distinctive feature of the presence of spontaneous chiral symmetry breaking in QCD is the condensation of low modes of the Dirac operator near the origin. The rate of condensatio…
