Sigma terms and strangeness content of the nucleon with twisted mass fermions
C. Alexandrou, M. Constantinou, S. Dinter +6
We investigate excited state contaminations in a direct computation of the nucleon -terms. This is an important source of systematic effects that needs to be controlled besides…
Overlap valence quarks on a twisted mass sea: a case study for mixed action Lattice QCD
Krzysztof Cichy, Vincent Drach, Elena Garcia-Ramos +2
We discuss a Lattice QCD mixed action investigation employing Wilson maximally twisted mass sea and overlap valence fermions. Using four values of the lattice spacing, we demonstra…
Properties of pseudoscalar flavour-singlet mesons from 2+1+1 twisted mass lattice QCD
Krzysztof Cichy, Vincent Drach, Elena Garcia-Ramos +5
We study properties of pseudoscalar flavour-singlet mesons from Wilson twisted mass lattice QCD with Nf=2+1+1 dynamical quark flavors. Results for masses are presented at three val…
Evaluation of disconnected contributions using GPUs
C. Alexandrou, V. Drach, K. Hadjiyiannakou +4
We calculate on GPUs the disconnected diagrams associated with the nucleon form factors and moments of generalized parton distributions using Nf=2+1+1 twisted mass fermions. We emp…
