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…
Higgs-Yukawa model in chirally-invariant lattice field theory
John Bulava, Philipp Gerhold, Karl Jansen +6
Non-perturbative numerical lattice studies of the Higgs-Yukawa sector of the standard model with exact chiral symmetry are reviewed. In particular, we discuss bounds on the Higgs b…
Non-perturbative renormalization in coordinate space for maximally twisted mass fermions with tree-level Symanzik improved gauge action
Krzysztof Cichy, Karl Jansen, Piotr Korcyl
We present results of a lattice QCD application of a coordinate space renormalization scheme for the extraction of renormalization constants for flavour non-singlet bilinear quark…
Nonperturbative QCD corrections to electroweak observables
Dru B. Renner, Xu Feng, Karl Jansen +1
Nonperturbative QCD corrections are important to many low-energy electroweak observables, for example the muon magnetic moment. However, hadronic corrections also play a significan…
Sigma terms and strangeness content of the nucleon with twisted mass fermions
Simon Dinter, Vincent Drach, Roberto Frezzotti +3
We study the nucleon matrix elements of the quark scalar-density operator using maximally twisted mass fermions with dynamical light (,), strange and charm degrees of freedom…
