Finite-volume effects on smeared spectral densities
Francesca A. Bresciani, Mattia Bruno, Maxwell T. Hansen
Using two distinct approaches, we derive a universal expression for the leading finite-volume effects of the smeared vector-vector spectral density (proportional to the smeared had…
Bounding statistical errors in lattice field theory simulations
Mattia Bruno, Gabriele Morandi
Simulations of strongly interacting lattice field theories are typically performed using Markov chain Monte Carlo algorithms. Therefore estimators of statistical errors must incorp…
Spectral densities from Euclidean-time lattice correlation functions
Matteo Saccardi, Mattia Bruno, Leonardo Giusti
In quantum field theories, spectral densities are directly related to relevant physical observables. In Lattice QCD, their non-perturbative extraction from first principles require…
Spectral densities from Euclidean lattice correlators via the Mellin transform
Mattia Bruno, Leonardo Giusti, Matteo Saccardi
Spectral densities connect correlation functions computed in quantum field theory to observables measured in experiments. For strongly-interacting theories, their non-perturbative…
On the prediction of spectral densities from Lattice QCD
Mattia Bruno, Leonardo Giusti, Matteo Saccardi
Hadronic spectral densities play a pivotal role in particle physics, a prime example being the R-ratio defined from electron-positron scattering into hadrons. To predict them from…
