Lattice calculation of the hadronic leading order contribution to the muon
H. Wittig, A. Gérardin, Marco Cè +9
The persistent discrepancy of about 3.5 standard deviations between the experimental measurement and the Standard Model prediction for the muon anomalous magnetic moment, , is…
The leading hadronic vacuum polarization contribution to the muon anomalous magnetic moment using O() improved Wilson quarks
Antoine Gérardin, Marco Cè, Georg von Hippel +6
We present a lattice calculation of the leading hadronic contribution to the anomalous magnetic moment of the muon. This work is based on a subset of the CLS ensembles with $N_f =…
Strange nucleon form factors and isoscalar charges with -improved Wilson fermions
Dalibor Djukanovic, Harvey Meyer, Konstantin Ottnad +3
We report on our calculation of the strange contribution to the vector and axial vector form factors. The strange charge radii, magnetic moment, and axial charge are extracted by m…
The hadronic contribution to the running of the electromagnetic coupling and the electroweak mixing angle
Marco Cè, Teseo San José, Antoine Gérardin +6
The electromagnetic coupling and the electroweak mixing angle are parameters of the Standard Model (SM) that enter precision SM tests and play a fundamental rô…
Nucleon isovector charges and twist-2 matrix elements with dynamical Wilson quarks
Tim Harris, Georg von Hippel, Parikshit Junnarkar +5
We present results from a lattice QCD study of nucleon matrix elements at vanishing momentum transfer for local and twist-2 isovector operator insertions. Computations are performe…
The leading hadronic contribution to from lattice QCD with flavours of O() improved Wilson quarks
Antoine Gérardin, Marco Cè, Georg von Hippel +6
The comparison of the theoretical and experimental determinations of the anomalous magnetic moment of the muon constitutes one of the strongest tests of the Standard Mode…
Strange electromagnetic form factors of the nucleon with -improved Wilson fermions
Dalibor Djukanovic, Konstantin Ottnad, Jonas Wilhelm +1
We present results for the strange contribution to the electromagnetic form factors of the nucleon computed on the CLS ensembles with flavors of -improved…
