Vision for QCD to the 2030s and Beyond
SciPost Physics Proceedings, 2022 In this closing talk, I review some of the lessons we've learned about quantum chromodynamics, and reflect on what we may hope to learn in the coming years.

New CTEQ global analysis of quantum chromodynamics with high-precision data from the LHC [PDF]
, 2019 We present the new parton distribution functions (PDFs) from the CTEQ-TEA collaboration, obtained using a wide variety of high-precision Large Hadron Collider (LHC) data, in addition to the combined HERA I+II deep-inelastic scattering data set, along ...

The L ∞ structure of gauge theories with matter
Journal of High Energy Physics, 2021 In this work we present an algebraic approach to the dynamics and perturbation theory at tree-level for gauge theories coupled to matter. The field theories we will consider are: Chern-Simons-Matter, Quantum Chromodynamics, and scalar Quantum ...

, 1995 These lectures provide an overview of Quantum Chromodynamics (QCD), the $SU(3)_C$ gauge theory of the strong interactions. After briefly reviewing the empirical considerations which lead to the introduction of {\it colour}, the QCD Lagrangian is ...

Multigrid multilevel Monte Carlo for a lattice with a displacement
PAMM, Volume 23, Issue 3, November 2023., 2023 Abstract The Hutchinson method can be used to estimate the trace of a function of a matrix A, that is, , stochastically. With the variance of the Hutchinson estimator decreasing as , techniques to reduce the variance of this estimator become necessary due to the high accuracy required by some calculations in scientific computing.

Deuteronlike Heavy Dibaryons from Lattice Quantum Chromodynamics. [PDF]
Physical Review Letters, 2019 We report the first lattice quantum chromodynamics (QCD) study of deuteronlike (np-like) dibaryons with heavy quark flavors. These include particles with the following dibaryon structures and valence quark contents: Σ_{c}Ξ_{cc}(uucucc), Ω_{c}Ω_{cc ...

Probabilistic Neural Computing with Stochastic Devices
Advanced Materials, Volume 35, Issue 37, September 14, 2023., 2023 Modern computing assumes that materials, devices, and circuits will be operated in a fully deterministic manner, providing predictable and reliable outputs, with any desired random behavior re‐introduced in software. This perspective describes how the integration of tunable stochastic devices into neuromorphic computing architectures can allow future ...

Journal of Advances in Modeling Earth Systems, Volume 15, Issue 5, May 2023., 2023 Abstract The ocean circulation dynamics can be represented as a high‐dimensional multi‐scale nonlinear system with inhomogenous meanfields and topography. Numerical simulations of the ocean dynamics resolve the large scales of motion on a computational grid, with the unresolved subgrid interactions parameterized.

A Possible Resolution to Troubles of SU(2) Center Vortex Detection in Smooth Lattice Configurations
Universe, 2021 The center vortex model of quantum-chromodynamics can explain confinement and chiral symmetry breaking. We present a possible resolution for problems of the vortex detection in smooth configurations and discuss improvements for the detection of center ...

Three Dimensional Quantum Chromodynamics [PDF]
, 1992 The subject of this talk was the review of our study of three ($2+1$) dimensional Quantum Chromodynamics. In our previous works, we showed the existence of a phase where parity is unbroken and the flavor group $U(2n)$ is broken to a subgroup $U(n)\times ...
