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…
Release Note - VBFNLO 2.7.0
J. Baglio, J. Bellm, F. Campanario +11
VBFNLO is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), double and triple vector boson (plus jet) production as well as QCD-induced s…
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…
Next-to-leading-order electroweak corrections to pp->WW->4 leptons in double-pole approximation at the LHC
M. Billoni, S. Dittmaier, B. Jager +1
We report on our calculation of next-to-leading-order electroweak corrections to W-boson pair production at the LHC, taking into account off-shell effects and spin correlations of…
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…

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…
