Theory Summary of the Hadron Structure and QCD Workshop 2008
N. G. Stefanis
This paper is the write-up version of the theory summary talk given at the HSQCD 2008 Workshop in Gatchina, Russia. Recent theoretical developments and results are summarized focus…
Renormalization-group approach to transverse-momentum dependent parton distribution functions in QCD
N. G. Stefanis, I. O. Cherednikov
We discuss the renormalization of gauge-invariant transverse-momentum dependent (TMD), i.e., unintegrated, parton distribution functions (PDFs) and carry out the calculation of the…
New results on gauge-invariant TMD PDFs in QCD
I. O. Cherednikov, N. G. Stefanis
The renormalization properties of unintegrated (transverse-momentum dependent) parton distribution functions (TMD PDF's) are used for analyzing their completely gauge-invariant def…
Anomalous dimensions of transverse-momentum dependent parton distribution functions
N. G. Stefanis, I. O. Cherednikov
We discuss recent developments in the understanding of gauge-invariant transverse-momentum dependent (TMD) parton-distribution functions (PDF). We compute the leading-order $\overl…
New vistas of the meson structure in QCD from low to high energies
N. G. Stefanis
This talk presents issues pertaining to the quark structure of the pion within QCD, both from the theoretical and from the experimental point of view. We review and discuss the pio…
Analyticity of QCD observables beyond leading-order perturbation theory
N. G. Stefanis, A. I. Karanikas
A theoretical framework is presented to treat hadronic observables within analytic perturbative QCD beyond the leading order of the coupling and for more than one single large mome…
