Abstract: | With the construction of high energy, high intensity accelerators (NAL & CERN, SPS) investigation of neutrino scattering on virtual pions, á la Chew-Low, becomes experimentally possible. We propose to analyse the process ν + N → μ? + K + Δ to extract the usual K?3 form factor(s) for spacelike momentum transfer. A model calculation suggests that f+(T) can be determined reasonably well from a triple differential cross section, whereas only rough information on f?(T) may be obtained from the transverse polarization of the muon. The experiment proposed requires scanning of several millions of bubble chamber pictures. |
