Abstract
Global properties of the hadronic final state in deep inelastic scattering events at HERA are investigated. The data are corrected for detector effects and are compared directly with QCD phenomenology. Energy flows in both the laboratory frame and the hadronic centre of mass system and energy-energy correlations in the laboratory frame are presented. Comparing various QCD models, the colour dipole model provides the only satisfactory description of the data. In the hadronic centre of mass system the momentum components of charged particles longitudinal and transverse to the virtual boson direction are measured and compared with lower energy lepton-nucleon scattering data as well as withe+e− dat from LEP.

Parton-based Gribov–Regge theory

TL;DR: In this article, a QCD-inspired parton model for the initial stage of nuclear collisions at very high energies (RHIC, LHC and beyond) is presented, which is a self-consistent treatment, using the same formalism for calculating cross sections and particle production.

A QCD model for jet fragmentation including soft gluon interference

TL;DR: In this paper, a new model for hadronic jet fragmentation in hard processes is presented based on a QCD parton branching mechanism with correct treatment of leading collinear and infra-red singularities (i.e. including soft gluon interference).

Monte Carlo simulation of general hard processes with coherent QCD radiation

TL;DR: In this paper, the authors extended their previous work on the simulation of coherent soft-gluon radiation to hard collisions that involve incoming as well as outgoing coloured partons, and proposed a new Monte Carlo program which incorporates this procedure, together with other new features such as azimuthal correlations due to gluon polarization and interference.
