The cross section is measured for the lljj (l = e, mu) final state in the kinematic region m(ll) > 50 GeV, m(jj) > 120 GeV, transverse momenta p(T)(j) > 25 GeV and pseudorapidity vertical bar eta(j)vertical bar < 4.0. The measurement, combining the muon and electron channels, yields sigma = 154 +/- 24 (stat.) +/- 46 (exp. syst.) +/- 27 (th. syst.) +/- 3 (lum.) fb, in agreement with the theoretical cross section. The hadronic activity, in the rapidity interval between the jets, is also measured. These results establish an important foundation for the more general study of vector boson fusion processes, of relevance for Higgs boson searches and for measurements of electroweak gauge couplings and vector boson scattering.
