The hadronic vacuum polarization contribution to the muon from lattice QCD
M. Della Morte, A. Francis, V. Gülpers +7
We present a calculation of the hadronic vacuum polarization contribution to the muon anomalous magnetic moment, , in lattice QCD employing dynamical up and down…
Study of the hadronic contributions to the running of the QED coupling and the weak mixing angle
Anthony Francis, Vera Gülpers, Gregorio Herdoíza +4
The electromagnetic coupling receives significant contributions to its running from non-perturbative QCD effects. We present an update of a lattice QCD study of the Adler function…
Study of the Couplings of QED and QCD from the Adler Function
Anthony Francis, Gregorio Herdoíza, Hanno Horch +3
The contribution from hadronic vacuum polarisation effects is responsible for a large fraction of the theoretical uncertainty in the running of the QED coupling. The current level…
Nucleon axial form factors from two-flavour Lattice QCD
P. M. Junnarkar, S. Capitani, D. Djukanovic +6
We present preliminary results on the axial form factor and the induced pseudoscalar form factor of the nucleon. A systematic analysis of the excited-state co…
The leading hadronic contribution to (g-2) of the muon: The chiral behavior using the mixed representation method
Anthony Francis, Vera Guelpers, Gregorio Herdoiza +4
We extend our analysis of the leading hadronic contribution to the anomalous magnetic moment of the muon using the mixed representation method to study its chiral behavior. We pres…
Computing the Adler function from the vacuum polarization function
Hanno Horch, Michele Della Morte, Gregorio Herdoíza +3
We use a lattice determination of the hadronic vacuum polarization tensor to study the associated Ward identities and compute the Adler function. The vacuum polarization tensor is…
Adler function and hadronic vacuum polarization from lattice vector correlators
Anthony Francis, Benjamin Jäger, Harvey B. Meyer +1
We study a representation of the hadronic vacuum polarization based on the time-momentum representation of the vector correlator. This representation suggests a way to compute the…
A high-statistics study of the nucleon EM form factors, axial charge and quark momentum fraction
B. Jäger, T. D. Rae, S. Capitani +6
We present updated results for the nucleon axial charge and electromagnetic (EM) form factors, which include a significant increase in statistics for all ensembles (up to 4000 meas…
Improved interpolating fields for hadrons at non-zero momentum
Michele Della Morte, Benjamin Jaeger, Thomas Rae +1
We generalize Gaussian/Wuppertal smearing in order to produce non-spherical wave functions. We show that we can achieve a reduction in the noise-to-signal ratio for correlation fun…
The nucleon axial charge from lattice QCD with controlled errors
S. Capitani, M. Della Morte, G. von Hippel +5
We report on our calculation of the nucleon axial charge gA in QCD with two flavours of dynamical quarks. A detailed investigation of systematic errors is performed, with a particu…
Towards a precise lattice determination of the leading hadronic contribution to (g-2)_mu
Michele Della Morte, Benjamin Jäger, Andreas Jüttner +1
We report on our computation of the leading hadronic contribution to the anomalous magnetic moment of the muon using two dynamical flavours of non-perturbatively O(a) improved Wils…
The leading hadronic vacuum polarisation on the lattice
Michele Della Morte, Benjamin Jager, Andreas Juttner +1
After discussing the relevance of a first principles theory-prediction of the hadronic vacuum polarisation for Standard Model tests, the theoretical challenges for its computation…
