From microscopic interactions to the dynamics of the fireball

open access: yesEPJ Web of Conferences, 2014

Non-perturbative QCD by lattice simulations [PDF]

open access: yes, 2010
We present a brief overview of the status of lattice QCD computations for the study of strong interactions in the non-perturbative regime. We focus in particular on the computational requirements and on results concerning the phase diagram of QCD at ...

Perturbative QCD in a non-perturbative vacuum

open access: yesPhysics Letters B, 1981
Abstract We propose a procedure for interpreting the presence of a background gluon field in the context of perturbative QCD. We expect our method to be useful when non-perturbative effects are significant but not completely dominant.

On the description of exotic hadron states within QCD sum rules

open access: yesEPJ Web of Conferences, 2017
Revisiting the QCD sum-rule description of exotic hadron states, we argue that, in order to arrive at trustable analyses of, for instance, strong decay widths of multiquarks, it is inevitable to adopt the QCD sum-rule approach beyond the leading ...

Controlling quark mass determinations non-perturbatively in three-flavour QCD

open access: yesEPJ Web of Conferences, 2017
The determination of quark masses from lattice QCD simulations requires a non-perturbative renormalization procedure and subsequent scale evolution to high energies, where a conversion to the commonly used MS¯$\overline {{\rm{MS}}} $ scheme can be safely

Analytic Perturbation Theory for QCD Observables

open access: yesTheoretical and Mathematical Physics, 2001
The connection between ghost-free formulations of RG-invariant perturbation theory in the both Euclidean and Minkowskian regions is studied. Our basic tool is the "double spectral representation", similar to definition of Adler function, that stems from first principles of local QFT.

Two loop vertices and tree level multicollinear limits in QCD [PDF]

open access: yes, 2005
We present a summary of the methods required to solve loop-integrals and their reduction to Master Integrals. We then present the expansion in d = 4 - 2e of the Master Integrals required for the two loop massless vertex diagrams with three off-shell legs.
