Renormalization-guided cascade upscaling for lattice field generation
Anna Hasenfratz, Ethan T. Neil, Letizia Parato +1
We introduce a renormalization-group (RG) guided machine-learning algorithm for lattice field generation based on approximate inversion of an RG transformation. A ``perfect blockin…
Renormalization-guided inverse blocking for lattice field generation: construction and validation
Anna Hasenfratz, Ethan T. Neil, Letizia Parato +1
We propose an algorithm for generating lattice field configurations based on the approximate inversion of a renormalization-group blocking transformation. We optimize the blocking…
Confinement transition to gravitational waves in the one-flavor Hyper Stealth Dark Matter theory
V. Ayyar, R. C. Brower, G. T. Fleming +11
The thermodynamics of the gauge theory with a single flavor of fundamental quarks is analyzed on the lattice with dynamical fermion simulations, which is the low-energy sec…
Hyper Stealth Dark Matter and Long-Lived Particles
George T. Fleming, Graham D. Kribs, Ethan T. Neil +2
A new dark matter candidate is proposed that arises as the lightest baryon from a confining gauge theory which equilibrates with the Standard Model only through electroweak…
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…
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…
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…
Maximum-Likelihood Approach to Topological Charge Fluctuations in Lattice Gauge Theory
R. C. Brower, M. Cheng, G. T. Fleming +11
We present a novel technique for the determination of the topological susceptibility (related to the variance of the distribution of global topological charge) from lattice gauge t…
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…
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…
