This report summarizes our study of Neutral Current (NC)-induced photonproduction in MiniBooNE, as motivated by the low energy excess in thisexperiment [A. A. Aquilar-Arevalo et al. (MiniBooNE Collaboration), Phys. Rev.Lett. 98, 231801 (2007); 103, 111801 (2009)]. It was proposed that NC photonproduction with two anomalous photon-$Z$ boson-vector meson couplings mightexplain the excess. However, our computed event numbers in both neutrino andantineutrino runs are consistent with the previous MiniBooNE estimate that isbased on their pion production measurement. Various nuclear effects discussedin our previous works, including nucleon Fermi motion, Pauli blocking, and the$\Delta$ resonance broadening in the nucleus, are taken into account.Uncertainty due to the two anomalous terms and nuclear effects are studied in aconservative way.

Can neutrino-induced photon production explain the low energy excess in MiniBooNE?
