BMW/DMZ calculation of the hadronic vacuum polarisation for the muon magnetic moment
Finn M. Stokes, Alessandro Cotellucci, Michel Davier +11
For twenty years, a persistent discrepancy between experimental measurements and theoretical calculations of the muon anomalous magnetic moment have provided tantalising hints of n…
Hybrid calculation of hadronic vacuum polarization in muon g-2 to 0.48\%
A. Boccaletti, Sz. Borsanyi, A. Cotellucci +19
We present a new lattice QCD calculation of the leading order hadronic vacuum polarization (LO-HVP) contribution to the muon anomalous magnetic moment . We reduce uncertainti…
The three-loop hadronic vacuum polarization in chiral perturbation theory
Mattias Sjö, Laurent Lellouch, Alessandro Lupo +2
Hadronic vacuum polarization is a key observable in low-energy QCD, and is famously the greatest contributor to the theoretical uncertainty in the muon magnetic moment. Its long-di…
Hadronic vacuum polarization to three loops in chiral perturbation theory
Laurent Lellouch, Alessandro Lupo, Mattias Sjö +2
Hadronic vacuum polarization at low virtualities limits the precision of experimental tests of the standard model via important physical observables. Here we compute that effect in…
Lattice calculation of the , and transition form factors and the hadronic light-by-light contribution to the muon
Antoine Gérardin, Willem E. A. Verplanke, Gen Wang +5
In this paper we present a first ab-initio calculation of the , and transition form factors performed with physical light-quark masses. We provide a comple…
QCD thermodynamics with dynamical chiral fermions
Z. Fodor, A. Yu. Kotov, T. G. Kovacs +1
We discuss properties of thermal Quantum Chromodynamics obtained by means of lattice simulations with overlap fermions. This fermion discretisation preserves chiral symmetry at fin…
