We provide a concise overview on transverse momentum dependent (TMD) parton
distribution functions, their application to topical issues in high-energy physics …

We study the connection between asymptotic symmetries in non-Abelian gauge theories
and the generalized coherent states following from the application to QCD of the Faddeev …

Calculation results for the HQET field anomalous dimension and the QCD cusp anomalous
dimension, as well as their properties, are reviewed. The HQET field anomalous dimension …

A bstract We perform a canonical transformation of fields that brings the Yang-Mills action in
the light-cone gauge to a new classical action, which does not involve any triple-gluon …

Observable states are gauge invariant. In a non-Abelian gauge theory, these are necessarily
composite operators. We investigate the spectrum of these operators in the two-Higgs …

A bstract The MHV action is the Yang-Mills action quantized on the light-front, where the two
explicit physical gluonic degrees of freedom have been canonically transformed to a new set …

We review the factorization of the $ S $-matrix elements in the context of particle scattering
off an external field, which can serve as a model for the field of a large nucleus. The …

We study the electron as a system composed of an electron and a photon, using lowest-
order perturbation theory. We derive the leading-twist transverse-momentum-dependent …

A bstract Particle detectors are an ubiquitous tool for probing quantum fields in the context of
relativistic quantum information (RQI). We formulate the Unruh-DeWitt (UDW) particle …

With the advent of very powerful particle accelerators, such as RHIC and the LHC, it
becomes possible to study QCD in high energy collisions, in which the gluon content of the …
