Abstract
Internal jet structure in dijet production in deep-inelastic scattering is measured with the H1 detector at HERA. Jets with transverse energies E-T,E- Breit > 5 GeV are selected in the Breit frame employing k(perpendicular to) and cone jet algorithms. In the kinematic region of squared momentum trans fers 10 < Q(2) less than or similar to 120 GeV2 and Bjorken-x values 2 x 10 (-4) less than or similar to x(Bj) less than or similar to 8 x 10(-3), jet shapes and subjet multiplicities are measured as a function of a resolution parameter. Distributions of both observables are corrected for detector ef fects and presented as functions of the transverse jet energy and jet pseud o-rapidity, Dependences of the jet shape and the average number of subjets on the transverse energy and the pseudo-rapidity of the jet are observed. W ith increasing transverse jet energies and decreasing pseudo-rapidities, i. e, towards the photon hemisphere. the jets are more collimated. QCD models give a fair description of the data.
