Weak Pion and Photon Production off Nucleons in a Chiral Effective Field Theory

Understand

Neutrino-induced pion and photon production from nucleons and nuclei are important for the interpretation of neutrino-oscillation experiments, and these processes are potential backgrounds in the MiniBooNE experiment [A.

• Pion and photon production are investigated at intermediate energies, where the $\Delta$ resonance becomes important.
