Parallel Session: Confinement II

Analytical properties of the gauge boson propagator in the confining theory

Abstract: We study the gauge boson propagator in the dual Abelian Higgs theory which confines electric charges. The confinement is due to dual Abrikosov-Nielsen-Olesen strings. We show that the infrared double pole $1/(p^2)^2$ in the propagator is absent due to the confinement phenomenon. Instead, specific angular singularities signal the eventual set in of the confinement. We confirm our predictions by numerical calculations and discuss infrared properties of the gluon propagator in (lattice) gluodynamics.
