Stealth dark matter spectrum using Laplacian Heaviside smearing and irreducible representations

R. C. Brower, Chris Culver, Kimmy K. Cushman, George Fleming et autres

We present nonperturbative lattice calculations in the quenched approximation of the low-lying meson and baryon spectrum of the SU(4) gauge theory with fundamental fermion constituents. This theory is one instance of stealth dark matter, a class of strongly coupled theories, where the …

Light scalar meson and decay constant in SU(3) gauge theory with eight dynamical flavors

R. C. Brower, Evan K. Owen, Claudio Rebbi, Chris Culver et autres

The SU(3) gauge theory with Nf=8 nearly massless Dirac fermions has long been of theoretical and phenomenological interest due to the near-conformality arising from its proximity to the conformal window. One particularly interesting feature is the emergence of a relatively light, stable …

The Ising Model on $\mathbb S^2$

Richard C. Brower, Evan K. Owen

We define a 2-dimensional Ising model on a triangulated sphere, $\mathbb S^2$, designed to approach the exact conformal field theory (CFT) in the continuum limit. Surprisingly, the derivation leads to a set of geometric constraints that the lattice field theory must satisfy. …

Operator product expansion for radial lattice quantization of 3D ϕ4 theory

Venkitesh Ayyar, Richard C. Brower, George Fleming, Anna-Maria E. Glück et autres

At its critical point, the three-dimensional lattice Ising model is described by a conformal field theory (CFT), the 3D Ising CFT. Instead of carrying out simulations on Euclidean lattices, we use the quantum finite elements method to implement radially quantized critical ϕ4 …

Ising model on the affine plane

Richard C. Brower, Evan K. Owen

We demonstrate that the Ising model on a general triangular graph with three distinct couplings ${K}_{1}$, ${K}_{2}$, and ${K}_{3}$ corresponds to an affine transformed conformal field theory (CFT). Full conformal invariance of the $c=1/2$ minimal CFT is restored by introducing a metric …
