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…

Certified spectral functions from lattice Monte Carlo data
Sophie Mutzel, Antoine Tilloy
The Monte Carlo method, applied to lattice quantum field theory, gives access to Euclidean correlation functions with well-understood error bars. Recovering the observables one car…

Extracting quantum field theory dynamics from an approximate ground state
Sophie Mutzel, Antoine Tilloy
We develop a linear-programming method to extract dynamical information from static ground-state correlators in quantum field theory. We recast the Källén-Lehmann inversion as a…
