### Measurement of the Azimuthal Correlation between the most Forward Jet and the Scattered Positron in Deep-Inelastic Scattering at HERA.

Lidia Goerlich
Deep-inelastic positron-proton scattering events at low $Q^2$ with a forward jet, produced at small angles with respect to the proton beam, are measured with the H1 detector at HERA. A subsample of events with an additional jet in the central region is also studied. For both samples differential cross sections and normalised distributions are measured as a function of the azimuthal angle difference, $\Delta \phi$, between the forward jet and the scattered positron in bins...
