Stealth dark matter spectrum using LapH and Irreps
Richard C. Brower, Christopher Culver, Kimmy K. Cushman +17
We present non-perturbative lattice calculations of the low-lying meson and baryon spectrum of the SU(4) gauge theory with fundamental fermion constituents. This theory is one inst…
Light Scalar Meson and Decay Constant in SU(3) Gauge Theory with Eight Dynamical Flavors
Lattice Strong Dynamics Collaboration, R. C. Brower, E. Owen +15
The SU(3) gauge theory with nearly massless Dirac fermions has long been of theoretical and phenomenological interest due to the near-conformality arising from its proximit…
Hidden Conformal Symmetry from the Lattice
LSD Collaboration, T. Appelquist, R. C. Brower +14
We analyze newly expanded and refined data from lattice studies of an SU(3) gauge theory with eight Dirac fermions in the fundamental representation. We focus on the light composit…
Multigrid for Chiral Lattice Fermions: Domain Wall
Richard C. Brower, M. A. Clark, Dean Howarth +1
Critical slowing down for the Krylov Dirac solver presents a major obstacle to further advances in lattice field theory as it approaches the continuum solution. We propose a new mu…
Lattice Gauge Theory for Physics Beyond the Standard Model
Richard C. Brower, Anna Hasenfratz, Ethan T. Neil +7
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice field theory research to make an impact on models of new ph…
Nonperturbative investigations of SU(3) gauge theory with eight dynamical flavors
Lattice Strong Dynamics, Collaboration, : +14
We present our lattice studies of SU(3) gauge theory with = 8 degenerate fermions in the fundamental representation. Using nHYP-smeared staggered fermions we study finite-tem…
