Δ-mediated pion production in nuclei
Δ-mediated pion production in nuclei
We present a fully relativistic formalism for describing neutrino-induced \ensuremath{\Delta}-mediated single-pion production in nuclei. We assess the ambiguities stemming from the \ensuremath{\Delta} interactions and quantify the uncertainties in the axial form-factor parameters by comparing with the available bubble-chamber neutrino-scattering data. To include nuclear effects, we turn to a relativistic plane-wave …
