Exclusive results for the e−A→ X reaction — •Oliver Buss, Tina Leitner, and Ulrich Mosel — Institut für Theoretische Physik, Universität Gießen
We investigate electron scattering off nuclei using a transport approach for the description of the the final state interactions. Our major aim is the description of exclusive observables such as pion production and nucleon knockout within the kinematical range of W<2 GeV and Q2<2 GeV2.
The nuclear ground state is modeled within a local Thomas-Fermi approach including mean fields and realistic density distributions. For the e−A reaction we apply impulse approximation and include quasi-elastic scattering, resonance excitations and direct pion production for the initial vertex. The particles being produced in the initial reaction are transported out of the nucleus using the GiBUU off-shell transport model which allows for a full coupled channel treatment of the final state interactions.
Within the same framework, also pion production in neutrino nucleus scattering can be analyzed. The good description of electron scattering serves as a benchmark for this reaction which is an essential background for current neutrino oscillation experiments.
