Particle production and saturation at HERA

الأصل · EN

Perturbative QCD in the high-energy limit describes the evolution of scattering amplitudes with increasing energy towards and into the so-called saturation regime. Comparisons of the predictions with experimental data for a number of observables led to significant progress and understanding. We discuss the case of particle-production cross-sections measured at HERA and argue that these measurements have the potential to provide evidence for the saturation regime of QCD.
