New extended interpolating operators for hadron correlation functions
Francesco Scardino, Mauro Papinutto, Stefan Schaefer
New extended interpolating operators made of quenched three dimensional fermions are introduced in the context of lattice QCD. The mass of the 3D fermions can be tuned in a control…
Domain decomposition and multilevel integration for fermions
Marco Cè, Leonardo Giusti, Stefan Schaefer
The numerical computation of many hadronic correlation functions is exceedingly difficult due to the exponentially decreasing signal-to-noise ratio with the distance between source…
The determination of by the ALPHA collaboration
Mattia Bruno, Mattia Dalla Brida, Patrick Fritzsch +6
We review the ALPHA collaboration strategy for obtaining the QCD coupling at high scale. In the three-flavor effective theory it avoids the use of perturbation theory at a…
The large limit of the topological susceptibility of Yang-Mills gauge theory
Marco Cè, Miguel García Vera, Leonardo Giusti +1
We present a precise computation of the topological susceptibility of SU Yang-Mills theory in the large limit. The computation is done on the lattice, u…
A local factorization of the fermion determinant in lattice QCD
Marco Cè, Leonardo Giusti, Stefan Schaefer
We introduce a factorization of the fermion determinant in lattice QCD with Wilson-type fermions that leads to a bosonic action which is local in the block fields. The interaction…
Setting the scale for the CLS flavor ensembles
Mattia Bruno, Tomasz Korzec, Stefan Schaefer
We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale , which allow to set the scale of the lattices gen…
The topological susceptibility in the large-N limit of SU(N) Yang-Mills theory
Marco Cè, Miguel García Vera, Leonardo Giusti +1
We compute the topological susceptibility of the SU(N) Yang-Mills theory in the large-N limit with a percent level accuracy. This is achieved by measuring the gradient-flow definit…
Domain decomposition, multi-level integration and exponential noise reduction in lattice QCD
Marco Cè, Leonardo Giusti, Stefan Schaefer
We explore the possibility of computing fermionic correlators on the lattice by combining a domain decomposition with a multi-level integration scheme. The quark propagator is expa…
A multilevel algorithm for flow observables in gauge theories
Miguel García Vera, Stefan Schaefer
We study the possibility of using multilevel algorithms for the computation of correlation functions of gradient flow observables. For each point in the correlation function an app…
