Heavy quarkonium production in the Regge limit of QCD: from Tevatron to LHC

open access: yes, 2013
Heavy quarkonium production in the framework of the non-relativistic quantum chromodynamics and leading order of the parton Reggeization approach at the Tevatron and LHC is discussed.

Contemporary continuum QCD approaches to excited hadrons

open access: yesEPJ 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.

High-energy limit of quantum electrodynamics beyond Sudakov approximation

open access: yesPhysics 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.

Effective Fields in Dense Quantum Chromodynamics

open access: yes, 2002
In the high density, low temperature limit, Quantum Chromodynamics exhibits a transition to phases characterized by color superconductivity and energy gaps in the fermion spectra. We review some fundamental results obtained in this area and in particular

Chromoelectric flux tubes within non-Abelian Proca theory

open access: yesEuropean 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 ...

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

open access: yesPhysics 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.

Path Integrals in Lattice Quantum Chromodynamics

open access: yes, 2007
I discuss the use of path integrals to study strong-interaction physics from first principles. The underlying theory is cast into path integrals which are evaluated numerically using Monte Carlo methods on a space-time lattice.

New tests of quantum mechanics with unstable nuclei

open access: yesPhysics 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.
