Study of the parity violation in the delta region — •Luigi Capozza — Institut für Kernphysik, Johannes-Gutenberg-Universität Mainz, 55099 Mainz

A measurement of the parity violation asymmetry in electron-proton scattering using a polarized electron beam is performed at MAMI. So far the asymmetry has been fully extracted and interpreted for the elastic part of the observed spectrum.
With the same apparatus, inelastic processes are recorded in parallel to the elastic scattering events. Contributions to the inelastic spectrum arise from processes such as resonance excitation, pion production and other processes. In order to study parity violation in inelastic processes in the observed spectrum, it is important to recognize which phenomena are responsible for the experimental spectrum and with which magnitude.
The aim of this work is a simulation including all relevant processes in order to extract an estimate of the parity violation asymmertry in the delta region.
