Equivariant flow-based sampling for lattice gauge theory
Gurtej Kanwar, Michael S. Albergo, Denis Boyda +5
We define a class of machine-learned flow-based sampling algorithms for lattice gauge theories that are gauge-invariant by construction. We demonstrate the application of this fram…
Towards a composite Higgs and a partially composite top quark
B. Svetitsky, V. Ayyar, T. DeGrand +5
We have calculated quantities of interest to a theory of compositeness. The lattice model, approximating the candidate theory, is the SU(4) gauge theory coupled to fermions in two…
Radiative contribution to the composite-Higgs potential in a two-representation lattice model
Venkitesh Ayyar, Maarten Golterman, Daniel C. Hackett +4
Working in a two-representation lattice gauge theory that is close to a composite Higgs model, we calculate the low-energy constant CLR which controls the contribution of the elect…
Partial compositeness and baryon matrix elements on the lattice
Venkitesh Ayyar, Thomas DeGrand, Daniel C. Hackett +4
Partial compositeness is a mechanism for the generation of fermion masses which replaces a direct Higgs coupling to the fermions by a linear mixing with heavy composite partners. W…
Digitizing Gauge Fields: Lattice Monte Carlo Results for Future Quantum Computers
Daniel C. Hackett, Kiel Howe, Ciaran Hughes +3
In the near-future noisy intermediate-scale quantum (NISQ) era of quantum computing technology, applications of quantum computing will be limited to calculations of very modest sca…
Lattice Gauge Theory
Hartmut Wittig
The status of lattice calculations in Quantum Field Theory is reviewed. A major part is devoted to recent progress in formulating exact chiral symmetry on the lattice. Another topi…
