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 flavor…
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…
Meson spectroscopy in the gauge theory with three antisymmetric fermions
Ed Bennett, Deog Ki Hong, Ho Hsiao +5
We report the results of an extensive numerical study of the lattice gauge theory with three (Dirac) flavors of fermion in the two-index antisymmetric representation. In th…
Progress on lattice study of the chimera baryon spectrum in Sp(4) gauge theory
C. -J. David Lin, Ed Bennett, Niccolò Forzano +7
Investigation of composite Higgs models (CHMs) is of importance in contemporary particle physics. In this article, we present lattice computations of the chimera baryon masses in $…
