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…
Continuum Goldstone spectrum of two-color QCD at finite density with staggered quarks
Jonas Wilhelm, Lukas Holicki, Dominik Smith +2
We carry out lattice simulations of two-color QCD and spectroscopy at finite density with two flavors of rooted-staggered quarks and a diquark source term. As in a previous four-fl…
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…
