| Abstract | The production of four or more jets is studied in neutral current
deep-inelastic scattering at low negative four momentum transfer squared
5 < Q^2 < 100 GeV^2. Jet cross sections are measured as a function of Q^2
and jet transverse momentum using the kt, anti-kt and SISCone jet algorithms.
The measurements are compared to QCD models based on O(alpha_s) matrix
elements with parton showers and fragmentation and for four-jets to
O(alpha_s^3) QCD calculations corrected for hadronisation effects. |
