Title: Photon emission in neutral current interactions with nucleons and nuclei

Abstract

We report on our study of photon emission induced by E{sub ν} ∼ 1 GeV (anti)neutrino neutral current interactions with nucleons and nuclei. This process is an important background for ν{sub e} appearance oscillation experiments. At the relevant energies, the reaction is dominated by the excitation of the Δ(1232) resonance but there are also non-resonant contributions that, close to threshold, are fully determined by the effective chiral Lagrangian of strong interactions. We have obtained differential and integrated cross section for the (anti)neutrino-nucleon scattering and compare them with previous results. Furthermore, we have extended the model to nuclear targets taking into account Fermi motion, Pauli blocking and the in-medium modifications of the Δ properties. This study is important in order to reduce systematic effects in neutrino oscillation experiments.
