Pair Bremstrahlung in Neutrino-Nucleus Collisions
Abstract
Bremstrahlung of charged lepton-antilepton pairs by neutrinos in the electromagnetic field of nuclei is of potential importance for neutrino physics in high Z environments and representative of a class of processes connecting leptonic electroweak sectors to real or virtual photons. Standard Model cross sections and distributions for first generation flavor production by both electron and muon neutrinos will be presented and can be used to estimate backgrounds to neutrino experiments, including flux normalization. The energy and angular distributions will be discussed via analytic approximations to the matrix elements. Event signatures and possible roles in stellar and laboratory neutrino physics will be addressed.
