Un-particle Effective Action
Patricio Gaete, Euro Spallucci
We study un-particle dynamics in the framework of standard quantum field theory. We obtain the Feynman propagator by supplementing standard quantum field theory definitions with in…
Remarks on confinement driven by axion-like particles in Yang-Mills theories
Patricio Gaete, Euro Spallucci
Features of screening and confinement are studied for a non-Abelian gauge theory with a mixture of pseudoscalar and scalar coupling, in the case where a constant chromo-electric, o…
Confinement from gluodynamics in curved space-time
Patricio Gaete, Euro Spallucci
We determine the static potential for a heavy quark-antiquark pair from gluodynamics in curved space-time. Our calculation is done within the framework of the gauge-invariant, path…
Static potential from spontaneous breaking of scale symmetry
Patricio Gaete, Eduardo Guendelman, Euro Spallucci
We determine the static potential for a heavy quark-antiquark pair from the spontaneous symmetry breaking of scale invariance in a non-Abelian gauge theory. Our calculation is done…
Lorentz invariance and unitarity in UV finite NCQFT
Anais Smailagic, Euro Spallucci
Ultraviolet finite quantum field theory on even dimensional noncommutative spacetime is formulated using coordinate coherent states. 2d spacetime is foliated into families of ortho…
