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.

Overall systematic error of 6 pct not included.

Corrected transverse energy-energy correlation TEEC as a function of omega (see text of paper for definition of omega - which effectively defines the distance between hadrons in the pseudorapidity and azimuthal angle). Overall systematic error of 12 pct is not included.

Charged particle spectra as a function of the Feynman x variable for different ranges of the hadronic mass W.
