Neutrino-induced coherent pion production off nuclei reexamined
Neutrino-induced coherent pion production off nuclei reexamined
It is pointed out that so far all theoretical estimates of coherent pion production off nuclei induced by neutrinos rely on the ``local approximation'' well known in photonuclear physics. The effects of dropping this approximation are discussed. It is found that in a plane wave approximation for the pion, the …
