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…
Resonant scattering in two-flavored Sp(4) lattice gauge theories
Ed Bennett, Yannick Dengler, Deog Ki Hong +8
We apply Lüscher's method to the vector channel of the scattering amplitude of Pseudo-Nambu-Goldstone-Bosons (PNGBs), in the lattice gauge theory coupled to flavors…
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…
Vector-channel scattering of dark particles in a Sp(4) gauge theory
Jong-Wan Lee, Ed Bennett, Yannick Dengler +8
We report new results obtained in our lattice studies of the gauge theory coupled to two fundamental Dirac fermions. This theory provides a candidate for the dynamical orig…
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…
