The running of the electroweak gauge couplings from first principles
Alessandro Conigli, Dalibor Djukanovic, Georg von Hippel +6
We present a high-precision calculation of the hadronic running of electroweak gauge couplings from first principles. Employing lattice QCD in the low-energy regime, we achieve per…
The strange and flavor-singlet axial form factors of the nucleon from lattice QCD
Alessandro Barone, Dalibor Djukanovic, Georg von Hippel +3
The singlet axial form factor of the nucleon provides essential input for a complete understanding of the nucleon axial structure. Together with the isovector and isoscalar octet c…
Strong coupling constant from the 1-loop improved static energy
Viljami Leino, Alexei Bazavov, Nora Brambilla +8
The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice…
The hadronic contribution to the running of the electroweak gauge couplings
Alessandro Conigli, Dalibor Djukanovic, Georg von Hippel +6
We present an updated determination of the hadronic vacuum polarization contribution to the running of the electromagnetic coupling , and of the el…
Precision lattice calculation of the hadronic contribution to the running of the electroweak gauge couplings
Alessandro Conigli, Dalibor Djukanovic, Georg von Hippel +6
We present an update of our lattice QCD determination of the hadronic contribution to the running of the electromagnetic coupling, , and of the ele…
The isoscalar octet axial form factor of the nucleon from lattice QCD
Alessandro Barone, Dalibor Djukanovic, Georg von Hippel +4
The isoscalar axial-vector form factor of the nucleon plays a key role in understanding the electroweak interaction of nucleons. For the interpretation of the spin structure of the…
