Disconnected quark loop contributions to nucleon observables in lattice QCD
A. Abdel-Rehim, C. Alexandrou, M. Constantinou +5
We perform a high statistics calculation of disconnected fermion loops on Graphics Processing Units for a range of nucleon matrix elements extracted using lattice QCD. The isoscala…
Evaluation of disconnected quark loops for hadron structure using GPUs
C. Alexandrou, M. Constantinou, V. Drach +5
A number of stochastic methods developed for the calculation of fermion loops are investigated and compared, in particular with respect to their efficiency when implemented on Grap…
Phase structure of a generalized Nambu Jona-Lasinio model with Wilson fermions in the mean field or large -expansion
V. Azcoiti, G. Di Carlo, E. Follana +2
We analyze the vacuum structure of a generalized lattice Nambu--Jona-Lasinio model with two flavors of Wilson fermions, such that its continuum action is the most general four-ferm…
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…
