Title: Nonperturbative investigations of SU(3) gauge theory with eight dynamical flavors

Abstract

We present our lattice studies of SU(3) gauge theory with Nf = 8 degenerate fermions in the fundamental representation. Using nHYP-smeared staggered fermions we study finite-temperature transitions on lattice volumes as large as L3×Nt=483×24, and the zero-temperature composite spectrum on lattice volumes up to 643×128. The spectrum indirectly indicates spontaneous chiral symmetry breaking, but finite-temperature transitions with fixed Nt≤24 enter a strongly coupled lattice phase as the fermion mass decreases, which prevents a direct confirmation of spontaneous chiral symmetry breaking in the chiral limit. In addition to the connected spectrum we focus on the lightest flavor-singlet scalar particle. We find it to be degenerate with the pseudo-Goldstone states down to the lightest masses reached so far by non-perturbative lattice calculations. Using the same lattice approach, we study the behavior of the composite spectrum when the number of light fermions is changed from eight to four. A heavy flavor-singlet scalar in the 4-flavor theory affirms the contrast between QCD-like dynamics and the low-energy behavior of the 8-flavor theory.

Strongly interacting dynamics and the search for new physics at the LHC

Journal Article Appelquist, T. ; Brower, R. C. ; Fleming, G. T. ; ... - Physical Review D

In this paper, we present results for the spectrum of a strongly interacting SU(3) gauge theory with N_f=8 light fermions in the fundamental representation. Carrying out nonperturbative lattice calculations at the lightest masses and largest volumes considered to date, we confirm the existence of a remarkably light singlet scalar particle. We explore the rich resonance spectrum of the 8-flavor theory in the context of the search for new physics beyond the standard model at the Large Hadron Collider (LHC). Connecting our results to models of dynamical electroweak symmetry breaking, we estimate the vector resonance mass to be about 2 TeVmore »« less

Dynamical symmetry breaking in lattice gauge theories

Thesis/Dissertation Svetitsky, B

We investigate dynamical breaking of chiral symmetry in quantum chromodynamics defined on a spatial lattice. Our formulation respects chiral symmetry by employing a long-range gradient for the fermion field. In the strong-coupling limit all states with non-zero electric flux are at very high energy, so that the set of degenerate ground states is comprised of all fermionic configurations which are color singlets site by site. We derive an effective Hamiltonian for the mesons in perturbation theory about this limit. Color and flavor are shown to be inessential and we consider the U(1) gauge theory with one flavor of four-component fermions.more »« less
Light flavor-singlet scalars and walking signals in $N_{f} = 8$ QCD on the lattice

Journal Article Aoki, Yasumichi ; Aoyama, Tatsumi ; Bennett, Ed ; ... - Physical Review D

Based on the highly improved staggered quark action, we perform in this paper lattice simulations of N_f = 8 QCD and confirm our previous observations, both of a flavor-singlet scalar meson (denoted as σ) as light as the pion and of various “walking signals” through the low-lying spectra, with higher statistics, smaller fermion masses m_f, and larger volumes. We measure M_π, F_π, M_ρ, M_a₀, M_a₁, M_b₁, M_N, M_σ, F_σ, (φφ) (both directly and through the Gell-Mann-Oakes-Renner relation), and the string tension. The data are consistent with the spontaneously broken phase of the chiral symmetry, in agreement with the previous results:more »« less

Stealth dark matter: Dark scalar baryons through the Higgs portal

Journal Article Appelquist, T. ; Brower, R. C. ; Buchoff, M. I. ; ... - Physical Review. D, Particles, Fields, Gravitation and Cosmology

We present a new model of "Stealth Dark Matter": a composite baryonic scalar of an SU(N_D) strongly coupled theory with even N_D ≥ 4. All mass scales are technically natural, and dark matter stability is automatic without imposing an additional discrete or global symmetry. Constituent fermions transform in vectorlike representations of the electroweak group that permit both electroweak-breaking and electroweak-preserving mass terms. This gives a tunable coupling of stealth dark matter to the Higgs boson independent of the dark matter mass itself. We specialize to SU(4), and investigate the constraints on the model from dark meson decay, electroweak precision measurements,more »« less
