Progress on lattice theories with Grid: Möbius domain wall fermions and continuum extrapolations
Gianmarco Simonetti, Ed Bennett, Peter A. Boyle +10
We present preliminary results obtained in the first extensive study of the Möbius domain wall fermion (MDWF) lattice formulation of the four-dimensional Sp(4) gauge theory coupled…
Symplectic lattice gauge theories in the Grid framework: domain wall fermions and continuum extrapolations
Ed Bennett, Peter A. Boyle, Luigi Del Debbio +10
We report the results of the first numerical lattice study using domain-wall fermions in the Sp(4) gauge theory coupled to two flavours of (Dirac) fermions, transforming in the fun…
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…
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…
