Abstract
A measurement is presented of dijet and 3-jet cross sections in low-\t\ dif fractive deep-inelastic scattering interactions of the type ep --> eXY, whe re the system X is separated by a large rapidity gap from a low-mass baryon ic system Y. Data taken with the H1 detector at HERA, corresponding to an i ntegrated luminosity of 18.0 pb(-1), are used to measure hadron level singl e and double differential cross sections for 4 < Q(2) < 80 GeV2, z(p) < 0.0 5 and pT,(jet) > 4 GeV. The energy flow not attributed to jets is also inve stigated. The measurements are consistent with a factorising diffractive ex change with trajectory intercept close to 1.2 and tightly; constrain the do minating diffractive gluon distribution. Viewed in terms of the diffractive scattering of partonic fluctuations of the photon, the data require the do minance of q (q) over barq over q (q) over bar states. Soft colour neutrali sation models in their present form cannot simultaneously reproduce the sha pes 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.
