On Impact of Nuclear Effects on Weak Pion Production in Sub 1 GeV Energy Region

Understand

Charged-current single pion production in scattering off 12C is investigated for neutrino energies up to 1 GeV.

• An impact of nuclear effects with in-medium modifications of the Delta(1232) resonance properties as well as an effective field theory nonresonant background contribution are discussed.
• Dependence of the fraction of Delta(1232) decays into npnh states on incident neutrino energy is estimated.
• A model of Nieves et al.
