Scattering amplitudes beyond the planar limit of quantum chromodynamics

Scattering amplitudes provide insight into the all-orders structure of gauge theories. Particularly rich is their non-planar sector, where new and interesting physical phenomena appear.

Quark confinement in quantum chromodynamics

, 1989
Modern theories of elementary particles are based on principles such as symmetry and simplicity. This does not mean that it is always easy to extract predictions from them concerning phenomena.

Chromoelectric flux tubes within non-Abelian Proca theory

European Physical Journal C: Particles and Fields
Flux tube solutions within non-Abelian SU(3) Proca theory with external sources are obtained. It is shown that such tubes have a longitudinal chromoelectric field possessing two components (nonlinear and gradient), as well as a transverse chromomagnetic ...

Quantum Chromodynamics and Collider Processes

, 2013
These lectures notes on quantum chromodynamics aim at reviewing the status of today’s theoretical description of Standard Model processes relevant for Tevatron and Large Hadron Collider analyses, and of the tools that are used in phenomenological studies.

Quantum Chromodynamics

, 2006
After a brief historical review of the emergence of QCD as the quantum field theory of strong interactions, the basic notions of colour and gauge invariance are introduced leading to the QCD Lagrangian. The second lecture is devoted to perturbative QCD, from tree-level processes to higher-order corrections in renormalized perturbation theory, including

High-energy limit of quantum electrodynamics beyond Sudakov approximation

Physics Letters B, 2015
We study the high-energy behavior of the scattering amplitudes in quantum electrodynamics beyond the leading order of the small electron mass expansion in the leading logarithmic approximation.

New tests of quantum mechanics with unstable nuclei

Physics Letters B
We propose and analyze two new tests of quantum mechanics that would probe the time evolution of unstable nuclei. The first is a search for a time-dependent nuclear magnetic moment in radioisotopes over several half-lives.

K− over K+ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy

Physics Letters B, 2018
The K− over K+ multiplicity ratio is measured in deep-inelastic scattering, for the first time for kaons carrying a large fraction z of the virtual-photon energy.

Contemporary continuum QCD approaches to excited hadrons

EPJ Web of Conferences, 2016
Amongst the bound states produced by the strong interaction, radially excited meson and nucleon states offer an important phenomenological window into the long-range behavior of the coupling constant in Quantum Chromodynamics.
