Coulomb's law corrections from a gauge-kinetic mixing
Patricio Gaete, Iván Schmidt
We study the static quantum potential for a gauge theory which includes the mixing between the familiar photon and a second massive gauge field living in the so-called…
Modular application of an Integration by Fractional Expansion (IBFE) method to multiloop Feynman diagrams
Ivan Gonzalez, Ivan Schmidt
We present an alternative technique for evaluating multiloop Feynman diagrams, using the integration by fractional expansion method. Here we consider generic diagrams that contain…
A note on unparticle in lower dimensions
Patricio Gaete, Euro Spallucci
Using the gauge-invariant but path-dependent variables formalism, we examine the effect of the space-time dimensionality on a physical observable in the unparticle scenario. We exp…
Fourier transforms of UD integrals
Igor Kondrashuk, Anatoly Kotikov
UD integrals published by N. Usyukina and A. Davydychev in 1992-1993 are integrals corresponding to ladder-type Feynman diagrams. The results are UD functions where …
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…
