Extraction of spectral densities from lattice correlators: decoupling signal from noise
Alessandro Lupo, Nazario Tantalo
We expand the treatment of the problem of the extraction of smeared spectral densities from Euclidean correlators introduced in [Phys. Rev. D 99, 094508], providing an alternative…
Lattice studies of chimera baryons in Sp(4) gauge theory
Jong-Wan Lee, Ed Bennett, Luigi Del Debbio +10
We study chimera baryons, fermion bound states composed of two (hyper)quarks transforming in the fundamental and one in the antisymmetric representation of a non-Abelian gauge grou…
Chimera baryons and mesons on the lattice: a spectral density analysis
Ed Bennett, Luigi Del Debbio, Niccolò Forzano +10
We develop and test a spectral-density analysis method, based on the introduction of smeared energy kernels, to extract physical information from two-point correlation functions co…
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…
