Gluon polarization tensor in color magnetic background

In SU(2) gluodynamics we calculate the gluon polarization tensor in an Abelian homogeneous magnetic field in one-loop order in the Lorentz background field gauge. It turned out to be non transversal and consisting of ten tensor structures and corresponding form factors four in color neutral and six in color charged sector. Seven tensor structures are transversal, three are not. The non transver...

Induced Gluon Radiation in a Qcd Medium

Soft gluon radiation induced by multiple scattering of a fast quark or gluon propagating through QCD matter is discussed. After revisiting the Landau-Pomeranchuk-Migdal effect in QED we show that large formation times of bremsstrahlung quanta determine the QCD radiation intensity (in analogy to QED) and derive the gluon energy spectrum. Coherent suppression takes place as compared to the Bethe-...

Multiple Collisions and Induced Gluon Bremsstrahlung in QCD ∗

Induced soft gluon bremsstrahlung associated with multiple collisions is calculated via perturbative QCD. We derive the non-abelian analog of the LandauPomeranchuk effect that suppresses induced soft radiation with formation times exceeding the mean free path, λ. The dependence of the suppression effect on the SU(N) representation of the jet parton as well as the kinematic variables is expresse...

The Color–Flavor Transformation of induced QCD

The color–flavor transformation is applied to the U(Nc) lattice gauge model, in which the gauge theory is induced by a heavy chiral scalar field sitting on lattice sites. The flavor degrees of freedom can encompass several ‘generations’ of the auxiliary field, and for each generation, remaining indices are associated with the elementary plaquettes touching the lattice site. The effective, color...
