Gluon masses without seagull divergences
Joannis Papavassiliou
The study of dynamical gluon mass generation at the level of Schwinger-Dyson equation involves a delicate interplay between various field-theoretic mechanisms The underlying local…
Gluon mass generation without seagull divergences
Arlene C. Aguilar, Joannis Papavassiliou
Dynamical gluon mass generation has been traditionally plagued with seagull divergences, and all regularization procedures proposed over the years yield finite but scheme-dependent…
Non-perturbative QCD effective charges
Arlene C. Aguilar, Joannis Papavassiliou
Using gluon and ghost propagators obtained from Schwinger-Dyson equations (SDEs), we construct the non-perturbative effective charge of QCD. We employ two different definitions, wh…
Scrutinizing the Green's functions of QCD: Lattice meets Schwinger-Dyson
Joannis Papavassiliou
The Green's functions of QCD encode important information about the infrared dynamics of the theory. The main non-perturbative tools used to study them are their own equations of m…
Pinch Technique: Theory and Applications
D. Binosi, J. Papavassiliou
We review the theoretical foundations and most important physical applications of the Pinch Technique (PT). This method allows the construction of off-shell Green's functions in no…
Indirect determination of the Kugo-Ojima function from lattice data
A. C. Aguilar, D. Binosi, J. Papavassiliou
We study the structure and non-perturbative properties of a special Green's function, u(q), whose infrared behavior has traditionally served as the standard criterion for the reali…
Non-perturbative comparison of QCD effective charges
A. C. Aguilar, D. Binosi, J. Papavassiliou +1
We study the non-perturbative behavior of two versions of the QCD effective charge, one obtained from the pinch technique gluon self-energy, and one from the ghost-gluon vertex. De…
