The hadronic vacuum polarization and automatic O(a) improvement for twisted mass fermions
Florian Burger, Grit Hotzel, Karl Jansen +1
The vacuum polarization tensor and the corresponding vacuum polarization function are the basis for calculations of numerous observables in lattice QCD. Examples are the hadronic c…
Lepton anomalous magnetic moments from twisted mass fermions
Florian Burger, Grit Hotzel, Karl Jansen +1
We present our results for the leading-order hadronic quark-connected contributions to the electron, the muon, and the tau anomalous magnetic moments obtained with four dynamical q…
Leading-order hadronic contribution to the anomalous magnetic moment of the muon from N_f=2+1+1 twisted mass fermions
Florian Burger, Xu Feng, Grit Hotzel +3
We present results for the leading order QCD correction to the anomalous magnetic moment of the muon including the first two generations of quarks as dynamical degrees of freedom.…
Towards thermodynamics with twisted mass quarks
Florian Burger, Grit Hotzel, Michael Müller-Preussker +2
We present preliminary results achieved within a recently started project dealing with QCD thermodynamics in the presence of a fully dynamical second quark family. We are employing…
Using analytic continuation for the hadronic vacuum polarization computation
Xu Feng, Shoji Hashimoto, Grit Hotzel +3
We present two examples of applications of the analytic continuation method for computing the hadronic vacuum polarization function in space- and time-like momentum regions. These…
Four-Flavour Leading-Order Hadronic Contribution To The Muon Anomalous Magnetic Moment
Florian Burger, Xu Feng, Grit Hotzel +3
We present a four-flavour lattice calculation of the leading-order hadronic vacuum polarisation contribution to the anomalous magnetic moment of the muon, , a…
Computing the hadronic vacuum polarization function by analytic continuation
Xu Feng, Shoji Hashimoto, Grit Hotzel +3
We propose a method to compute the hadronic vacuum polarization function on the lattice at continuous values of photon momenta bridging between the spacelike and timelike regions.…
Wilson loops to 20th order numerical stochastic perturbation theory
R. Horsley, G. Hotzel, E. -M. Ilgenfritz +6
We calculate Wilson loops of various sizes up to 20 loops in SU(3) pure lattice gauge theory at different lattice sizes for Wilson gauge action using the technique of numerical sto…
Very high order lattice perturbation theory for Wilson loops
R. Horsley, G. Hotzel, E. -M. Ilgenfritz +5
We calculate perturbative Wilson loops of various sizes up to loop order at different lattice sizes for pure plaquette and tree-level improved Symanzik gauge theories using…
