An update on the HVP contribution to in isoQCD from ETMC
Simone Bacchio, Alessandro De Santis, Antonio Evangelista +7
We present an update on the determination of the leading-order hadronic vacuum polarisation contribution to the muon anomalous magnetic moment in isospin-symmetric QCD by the Exten…
A Comprehensive Stress Test of Truncated Hilbert Space Bases against Green's function Monte Carlo in U(1) Lattice Gauge Theory
Timo Jakobs, Marco Garofalo, Tobias Hartung +5
A representation of Lattice Gauge Theories (LGT) suitable for simulations with tensor network state methods or with quantum computers requires a truncation of the Hilbert space to…
lattice gauge theories with Physics-Informed Neural Networks
Simone Romiti
We present an application of Physics-Informed Neural Networks (PINNs) to the study of lattice gauge theories. Our method enables the learning of eigenfunctions a…
Dynamics in Hamiltonian Lattice Gauge Theory: Approaching the Continuum Limit with Partitionings of SU
Timo Jakobs, Marco Garofalo, Tobias Hartung +4
In this paper, we investigate a digitised SU lattice gauge theory in the Hamiltonian formalism. We use partitionings to digitise the gauge degrees of freedom and show how to d…
Valence leading isospin breaking contributions to
Simone Bacchio, Antonio Evangelista, Roberto Frezzotti +6
By employing the RM123 approach to QCD+QED, we computed the valence quark-connected isospin-breaking corrections to the light, strange and charm contributions at leading order in $…
Hadronic light-by-light contribution to the muon using twisted-mass fermions
Nikolaos Kalntis, Gurtej Kanwar, Marcus Petschlies +2
We report on our preliminary results from the lattice-QCD computation of the hadronic light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon. We use twiste…
