Progress on the spectroscopy of lattice gauge theories using spectral densities
Ed Bennett, Luigi Del Debbio, Niccolò Forzano +10
Spectral densities encode non-perturbative information crucial in computing physical observables in strongly coupled field theories. Using lattice gauge theory data, we perform a s…
Approaches to the Inverse Problem
Luigi Del Debbio, Alessandro Lupo, Marco Panero +1
The analytical continuation of correlation functions from imaginary to real time is a crucial step in lattice gauge theories, and it challenges our ability to derive non-perturbati…
Bayesian solution to the inverse problem and its relation to Backus-Gilbert methods
Luigi Del Debbio, Alessandro Lupo, Marco Panero +1
The problem of obtaining spectral densities from lattice data has been receiving great attention due to its importance in our understanding of scattering processes in Quantum Field…
Meson spectroscopy from spectral densities in lattice gauge theories
Ed Bennett, Luigi Del Debbio, Niccolò Forzano +10
Spectral densities encode non-perturbative information that enters the calculation of a plethora of physical observables in strongly coupled field theories. Phenomenological applic…
