Neutrino induced weak pion production off the nucleon and coherent pion production in nuclei at low energies
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 …
