| Abstract |
Deep-inelastic ep scattering data, taken with the H1 detector at HERA,
are used to investigate jet production
over a range of four-momentum transfers 150 < Q^2 < 15 000 GeV^2 and
transverse jet energies 5 < E_T < 50 GeV.
The analysis is based on data corresponding to an integrated luminosity
of L_int \simeq 65 pb^(-1) taken in the years 1999-2000 at a
center-of-mass energy sqrt(s)=319 GeV.
Jets are defined by the inclusive k_perp algorithm in the Breit frame of
reference.
Inclusive, Dijet and three-jet jet cross sections are measured
multi-differentially, in addition the ratio of the three-jet to the dijet
cross section R_(3/2) is investigated.
The results are compared to the predictions of perturbative QCD
calculations in next-to-leading order in the strong coupling constant
alpha_s. |
