Neutrino induced weak pion production off the nucleon and coherent pion production in nuclei at low energies
We present a microscopic model for neutrino induced one-pion production off the nucleon and its implementation for the purpose of calculating coherent pion production in nuclei. We further criticize the use of the Rein–Sehgal model for coherent pion production by low energy neutrinos. In particular, we show how the approximations in that model give rise to a much flatter differential cross sect...
متن کامل2 Final State Interactions in Pion Production from Nuclei
We have calculated the effect of the inclusion of final state interactions on pion production from nuclei with incident pion beams. We find that the effect of absorption , along with geometric considerations, explains much of the enhancement at low invariant mass seen in recent data for invariant mass spectra with increasing atomic number. While the variation among nuclei is well reproduced for...
متن کاملDynamical Model of Coherent Electroweak Pion Production Reactions on Nuclei
We have developed a dynamical model for a unified description of the pion-nucleus scattering and photoand neutrino-induced coherent pion production on nuclei. Our approach is based on a combined use of the Sato-Lee model for the electroweak pion production on a single nucleon and the ∆-hole model of pion-nucleus scattering. Numerical calculations are carried out for the case of the 12C target. ...
متن کاملNeutrino Induced Weak Pion Production off the Nucleon
We study neutrino induced one-pion production off the nucleon in and around the Delta resonance region. Apart from the Delta-pole mechanism we include background terms required by chiral symmetry. These background terms give sizeable contributions in all channels. To better reproduce the ANL q-differential cross section data, we make a new fit of the C 5 (q ) axial nucleon to Delta form factor....
متن کاملPion Rescattering in Nuclei
Nuclear corrections are presented for neutrino and electron induced reactions in a pedagogical manner. The formalism is demonstrated with numerical studies and is shown to produce substantial corrections in channels where the pions have the same charge with the exchanged current. Two comparisons with available data show consistency of the model. Additional experimental results along these lines...
