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…
Stochastic Path Sampler For Lattice Field Theory
Shiyang Chen, Moxian Qian, Gert Aarts +2
In lattice field theory, target distributions are known only up to normalization, (\tildeπ(ϕ)\propto e^{-S(ϕ)}), while the partition function is intractable. Markov chain Monte Car…
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…
Finite-temperature Sp(4) Yang-Mills theory: towards the continuum
Fabian Zierler, Ed Bennett, Biagio Lucini +4
We present numerical results obtained in a finite-temperature study of the Sp(4) Yang-Mills theory on the lattice. We study its first-order confinement/deconfinement phase transiti…
Simplicity of confinement in SU(3) Yang-Mills theory
Xavier Crean, Jeffrey Giansiracusa, Biagio Lucini
We introduce a novel observable associated to Abelian monopole currents defined in the Maximal Abelian Projection of SU(3) Yang-Mills theory that captures the topology of the curre…
