Two-Color Theory with Novel Infrared Behavior
T. Appelquist, R. C. Brower, M. I. Buchoff +13
Using lattice simulations, we study the infrared behavior of a particularly interesting SU(2) gauge theory, with six massless Dirac fermions in the fundamental representation. We c…
Goldstone Boson Scattering with a Light Composite Scalar
T. Appelquist, R. C. Brower, K. K. Cushman +14
The appearance of a light composite scalar resonance in nearly conformal gauge-fermion theories motivates further study of the low energy structure of these theories. To this…
The Physical Spectrum of Conformal SU(N) Gauge Theories
T. Appelquist, F. Sannino
We investigate the physical spectrum of vector-like SU(N) gauge theories with infrared coupling close to but above the critical value for a conformal phase transition. We use dispe…
Enhanced Global Symmetries and The Chiral Phase Transition
T. Appelquist, P. S. Rodrigues da Silva, F. Sannino
We examine the possibility that the physical spectrum of a vector-like gauge field theory exhibits an enhanced global symmetry near a chiral phase transition. A transition from the…
The Electroweak Chiral Lagrangian and New Precision Measurements
T. Appelquist, G. Wu
A revised and complete list of the electroweak chiral lagrangian operators up to dimension-four is provided. The connection of these operators to the , and parameters an…
Phases of Chiral Gauge Theories
T. Appelquist, Z. Duan, F. Sannino
We discuss the behavior of two non-supersymmetric chiral SU(N) gauge theories, involving fermions in the symmetric and antisymmetric two-index tensor representations respectively.…
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…
Linear Sigma EFT for Nearly Conformal Gauge Theories
T. Appelquist, R. C. Brower, G. T. Fleming +11
We construct a generalized linear sigma model as an effective field theory (EFT) to describe nearly conformal gauge theories at low energies. The work is motivated by recent lattic…
Lattice simulations with eight flavors of domain wall fermions in SU(3) gauge theory
T. Appelquist, R. C. Brower, G. T. Fleming +13
We study an SU(3) gauge theory with Nf=8 degenerate flavors of light fermions in the fundamental representation. Using the domain wall fermion formulation, we investigate the light…
Lattice calculation of composite dark matter form factors
T. Appelquist, R. C. Brower, M. I. Buchoff +14
Composite dark matter candidates, which can arise from new strongly-coupled sectors, are well-motivated and phenomenologically interesting, particularly in the context of asymmetri…
