Study of $\nu_{\mu}$-CC Interactions in the Resonance Region Using NOMAD Data

Abstract

Neutrino induced pion production in the resonance region is one of the most important interaction modes for the current and future generation long-baseline neutrino oscillation experiments. It is also sensitive to nuclear effects, including fermi motion, initial-state nucleon correlations, and final-state interactions \textit{etc.}, which affect event topology and energy reconstruction of resonance interactions, and contribute to the systematic uncertainty for oscillation measurements. We present study of the $\nu_{\mu}$ charge current interactions in the resonance region using high-statistics, high-resolution NOMAD data. Constraint on nuclear effects is also discussed.
