Observability of glueball spectrum in QCD and the width of resonance
Marco Frasca
We prove a theorem in QCD stating that in the limit of strong coupling, , the observed spectrum of glueballs in QCD is the same of a pure Yang-Mills theory, being mixin…
Yang-Mills Propagators and QCD
Marco Frasca
We present a strong coupling expansion that permits to develop analysis of quantum field theory in the infrared limit. Application to a quartic massless scalar field gives a massiv…
Exact Massive Solutions of Classical Massless Field Theories
Marco Frasca
We give the exact solution of classical equation of motion of a quartic scalar massless field theory showing that this is massive and is represented by a superposition of free part…
Infrared QCD
Marco Frasca
We prove that Nambu-Jona-Lasinio model is an exact description of infrared QCD deriving it from QCD Lagrangian. The model we obtain is renormalizable and confining but, taking very…
Infrared behavior of the running coupling in scalar field theory
Marco Frasca
We compute the Green function of the massless scalar field theory in the infrared till the next-to-leading order, providing a fully covariant strong coupling expansion. Applying Ca…
