Hard exclusive reactions with electroweak probes — •Jens Ossmann — Institut fuer Theoretische Physik II, Ruhr-Universitaet Bochum, 44780 Bochum

We show how modern neutrino beams from muon storage rings can be used to aquire new information about generalized parton distributions in not too far future.

In particular we study the reaction ν_µ+ p→ µ⁺+ n +γ and compare it with deeply virtual Compton scattering (DVCS) which is shortly reviewed. Since this electroweak reaction can be described in terms of generalized parton distributions it can be used to check the result from DVCS. But due to its weak nature it is also a useful tool to explore new kinematical regions.
