Nonlinear QCD Evolution: Saturation without Unitarization
Alexander Kovner, Urs Achim Wiedemann
We consider the perturbative description of saturation based on the nonlinear QCD evolution equation of Balitsky and Kovchegov (BK). Although the nonlinear corrections lead to satu…
Eikonal Evolution and Gluon Radiation
Alex Kovner, Urs Achim Wiedemann
We give a simple quantum mechanical formulation of the eikonal propagation approximation, which has been heavily used in recent years in problems involving hadronic interactions at…
Z(N) wall junctions: Monopole fossils in hot QCD
Alex Kovner
We point out that the effective action of hot Yang--Mills theories has semi-classical solutions, which are naturally identified with monopole world lines, ``frozen'' into the short…
The chicken or the egg; or Who ordered the chiral phase transition?
Ian I. Kogan, Alex Kovner, Bayram Tekin
We draw an analogy between the deconfining transition in the 2+1 dimensional Georgi-Glashow model and the chiral phase transition in 3+1 dimensional QCD. Based on the detailed anal…
