The hadronic vacuum polarization contribution to from flavours of O() improved Wilson quarks
Antoine Gérardin, Tim Harris, Georg von Hippel +5
We report on our ongoing project to determine the leading-order hadronic vacuum polarisation contribution to the muon , using ensembles with flavours of O() impro…
The leading hadronic contribution to the running of the Weinberg angle using covariant coordinate-space methods
Marco Cè, Antoine Gérardin, Konstantin Ottnad +1
We present a preliminary study of the leading hadronic contribution to the running of the Weinberg angle . The running is extracted from the correlation function of…
A new method for suppressing excited-state contaminations on the nucleon form factors
Harvey B. Meyer, Konstantin Ottnad, Tobias Schulz
One of the most challenging tasks in lattice calculations of baryon form factors is the analysis and control of excited-state contaminations. Taking the isovector axial form factor…
Strange nucleon form factors with O()-improved Wilson fermions
Dalibor Djukanovic, Harvey Meyer, Konstantin Ottnad +3
We present preliminary results for strangeness form factors of the nucleon computed on the CLS ensembles with flavors of O()-improved Wilson fermions. Our calculations…
Nucleon charges and quark momentum fraction with Wilson fermions
Konstantin Ottnad, Tim Harris, Harvey Meyer +3
We present a nucleon structure analysis including local isovector charges as well as twist-2 operator insertions. Computations are performed on CLS ensembles with Wilson…
