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…
Low lying baryon spectrum with dynamical twisted quarks
Vincent Drach, Karl Jansen, Jaume Carbonell +2
We present first results on the octet and decuplet strange baryon spectrum with twisted mass quarks. We use an Osterwalder Seiler valence strange quark with a mass tune…
Strange and charmed baryons using N_f=2 twisted mass QCD
Mauro Papinutto, Jaume Carbonell, Vincent Drach +1
We compute the mass spectrum for strange/charmed baryons in the partially quenched approach using N_f=2 twisted mass QCD configurations. We investigate two main issues: the size of…
