From Static Potentials to High-Energy Scattering
… model for a unified description of static color dipole potentials, confining QCD strings, and hadronic high-energy reactions with special emphasis on saturation effects manifesting S-matrix unitarity at ultra-high energies. The model combines perturbative gluon exchange with the …

High-Energy Amplitudes in Gauge Theories in the Next-to-Leading-Order
… and then we calculate the NLO evolution of the color dipoles in the conformal <em>N</em>=4 SYM theory. To this end we define the "composite dipole operator" with the rapidity cutoff preserving conformal invariance, and the resulting Möbius invariant kernel for this operator agrees with the …

Running Coupling Constant and Transition From Low to High Energies in Quantum Chromodynamics
<p>The remarkable feature of QCD is that the coupling constant (the strength of the interaction) depends on the energy of the interacting particles. At high energies, the coupling constant vanishes and QCD becomes asymptotically free. However, at lower energy, the running coupling constant …
