Learning Low-Order Approximations of the Quark Propagator in Lattice QCD
Simon Pfahler, Maren Käfferlein, Daniel Knüttel +2
The hopping expansion is an important approximation of the quark propagator in lattice quantum chromodynamics, but it diverges for light quarks, which limits the scope of strong-co…
Isospin breaking corrections to the hadronic vacuum polarization with stochastic coordinate sampling
Mattia Bruno, Vera Gülpers, Nils Hermansson-Truedsson +3
In the recent Muon g-2 Theory Initiative white paper update, the hadronic vacuum polarization (HVP) contribution -- which dominates the theoretical uncertainty -- is evaluated as a…
A novel gauge-equivariant neural-network architecture for preconditioners in lattice QCD
Simon Pfahler, Daniel Knüttel, Christoph Lehner +1
Lattice QCD simulations are computationally expensive, with the solution of the Dirac equation being the major computational bottleneck of many calculations. We introduce a novel g…
Improvement in Autocorrelation Times Measured by the Master-Field Technique using Field Transformation HMC in 2+1 Domain Wall Fermion Simulations
Shuhei Yamamoto, Peter Boyle, Taku Izubuchi +3
The Field-Transformation Hybrid Monte-Carlo (FTHMC) algorithm potentially mitigates the issue of critical slowing down by combining the HMC with a field transformation, originally…
Extended framework for the hybrid Monte Carlo in lattice gauge theory
Norman H. Christ, Lu-Chang Jin, Christoph Lehner +2
We develop an extended framework for the hybrid Monte Carlo (HMC) algorithm in lattice gauge theory by embedding the group into the space of general complex matrices,$M_N(\…
Lattice QCD calculation of the -pole contribution to the hadronic light-by-light scattering in the anomalous magnetic moment of the muon
Tian Lin, Mattia Bruno, Xu Feng +4
We develop a method to compute the pion transition form factor directly at arbitrary space-like photon momenta and use it to determine the -pole contribution to the hadronic l…
Lattice calculation of the leading strange quark-connected contribution to the muon
T. Blum, P. A. Boyle, L. Del Debbio +9
We present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performe…
