50 Years of quantum chromodynamics [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be described by a local SU(3) gauge symmetry with charges called “color quantum numbers”, is reviewed; the goal of this review is to provide advanced Ph.D.

Differential Dyson–Schwinger equations for quantum chromodynamics [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Using a technique devised by Bender, Milton and Savage, we derive the Dyson–Schwinger equations for quantum chromodynamics in differential form. We stop our analysis to the two-point functions.

Simulating one-dimensional quantum chromodynamics on a quantum computer: Real-time evolutions of tetra- and pentaquarks [PDF]

open access: yesPhysical Review Research, 2023
Quantum chromodynamics (QCD)—the theory of quarks and gluons—has been studied for decades, but it is yet to be fully understood. A recent example is the prediction and experimental discovery of tetraquarks, which opened a new research field.

An equation-of-state-meter of quantum chromodynamics transition from deep learning

open access: yesNature Communications, 2018
The large data generated in heavy-ion collision experiments require careful analysis to understand the physics. Here the authors use the deep-learning method to sort equation of states in QCD transition and analyze the simulated data sets mimicking the ...

Advances in machine-learning-based sampling motivated by lattice quantum chromodynamics [PDF]

open access: yesNature Reviews Physics, 2023
Machine-learning-based sampling strategies have been recently developed for lattice quantum chromodynamics applications. These methods are in their early stages, but have the potential to enable currently intractable first-principles calculations in ...

Direct observation of the dead-cone effect in quantum chromodynamics [PDF]

open access: yesNature, 2021
In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD)1 ...

Quantum simulation of colour in perturbative quantum chromodynamics

open access: yesSciPost Physics, 2023
Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In this work, we present quantum gates that simulate the colour part of the interactions of quarks and gluons in perturbative quantum chromodynamics (QCD). As a

Diphoton Amplitudes in Three-Loop Quantum Chromodynamics. [PDF]

open access: yesPhysical Review Letters, 2020
We consider the three-loop scattering amplitudes for the production of a pair of photons in quark-antiquark annihilation in QCD. We use suitably defined projectors to efficiently calculate all helicity amplitudes.

Neural ordinary differential equation and holographic quantum chromodynamics [PDF]

open access: yesMachine Learning: Science and Technology, 2020
The neural ordinary differential equation (neural ODE) is a novel machine learning architecture whose weights are smooth functions of the continuous depth. We apply the neural ODE to holographic QCD by regarding the weight functions as a bulk metric, and
