Holographic analysis of near-conformal dynamics and light dilaton
Jesús Cruz Rojas, Deog Ki Hong, Sang Hui Im +1
We carry out a detailed analysis of the region slightly outside the conformal window of a non-trivial infrared fixed point in a generic bottom-up holographic setup. We focus on mod…
Numerical Study of Wheeler-Dewitt Equation beyond Slow-roll approximation
Jie Jiang, Deog Ki Hong, Dong-han Yeom
The Wheeler-DeWitt (WDW) equation is analyzed using two boundary proposals: the Hartle-Hawking no-boundary condition and tunneling condition. By compactifying the scale factor …
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 $…
Progress on the spectroscopy of an Sp(4) gauge theory coupled to matter in multiple representations
Ho Hsiao, Ed Bennett, Niccolò Forzano +7
We report progress on our lattice calculations for the mass spectra of low-lying composite states in the Sp(4) gauge theory coupled to two and three flavors of Dirac fermions trans…
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…
