Abstract

We carry out a series of studies on pion and photon productions in neutrino/electron/photon--nucleus scatterings. The low energy region is investigated by using a chiral effective field theory for nuclei. The results for the neutral current induced photon production (γ-NCP) are then extrapolated to neutrino energy E_ν∼ GeV region. By convoluting the cross sections with MiniBooNE's beam spectrum and detection efficiency, we estimate its γ-NCP, event number, and conclude that such photon production can not fully explain its low energy event excess in both neutrino and antineutrino runs.
