Query: Diffractive Dijet and 3-Jet Electroproduction at HERA   A new H1 measurement of diffractive dijet and 3-jet production cross sections
in diffractive deep inelastic scattering events of the type ep->eXY is
presented. The data constrain well the diffractive gluon distribution. At low
x-pom, a calculation based on perturbative QCD is in a reasonable agreement
with the data.
