Abstract

A measurement is presented of dijet and 3-jet cross sections in low-\t\ diffractive deep-inelastic scattering interactions of the type ep --> eXY, where the system X is separated by a large rapidity gap from a low-mass baryonic system Y. Data taken with the H1 detector at HERA, corresponding to an integrated luminosity of 18.0 pb(-1), are used to measure hadron level single and double differential cross sections for 4 < Q(2) < 80 GeV2, z(p) < 0.05 and pT,(jet) > 4 GeV. The energy flow not attributed to jets is also investigated. The measurements are consistent with a factorising diffractive exchange with trajectory intercept close to 1.2 and tightly; constrain the dominating diffractive gluon distribution. Viewed in terms of the diffractive scattering of partonic fluctuations of the photon, the data require the dominance of q (q) over barq over q (q) over bar states. Soft colour neutralisation models in their present form cannot simultaneously reproduce the shapes and the normalisations of the differential cross sections. Models based on 2-gluon exchange are able to reproduce the shapes of the cross sections at low x(p) values.
