Lattice determination of the higher-order hadronic vacuum polarization contribution to the muon
Arnau Beltran, Alessandro Conigli, Simon Kuberski +3
We present the first lattice QCD calculation of the next-to-leading order (NLO) hadronic vacuum polarization (HVP) contribution to the muon anomalous magnetic moment with sub-perce…
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 elec…
Heavy quark masses from step-scaling
Simon Kuberski, Alessandro Conigli, Patrick Fritzsch +6
We present a determination of the charm- and bottom-quark masses using the heavy-quark step-scaling strategy. Renormalization is performed in small volumes where relativistic botto…
Ground-State Extraction of Heavy-Light Meson Semileptonic Decay Form Factors
Antonino D'Anna, Alessandro Conigli, Patrick Fritzsch +7
We discuss the extraction of heavy-light pseudo-scalar to light pseudo-scalar decay form factors from finite time correlation functions. We place particular emphasis on the contami…
Hadronic physics from a Wilson fermion mixed-action approach: Setup and scale setting
Andrea Bussone, Alessandro Conigli, Julien Frison +6
We introduce a lattice QCD mixed action approach that employs Wilson-type quarks in the sea and valence sectors. The sea sector is based on gauge ensembles with fla…
Machine-learning techniques as noise reduction strategies in lattice calculations of the muon
Thomas Blum, Alessandro Conigli, Lukas Geyer +3
Lattice calculations of the hadronic contributions to the muon anomalous magnetic moment are numerically highly demanding due to the necessity of reaching total errors at the sub-p…
