Abstract
Using a high statistics sample of muon neutrino charged current quasielastic (CCQE) events, we report the first measurement of the double differential cross section (d2σdTμdcos θμ) for this process. The result features reduced model dependence and supplies the most complete information on neutrino CCQE scattering to date. Measurements of the absolute cross section as a function of neutrino energy (σ[EνQE,RFG]) and the single differential cross section (dσdQQE2) are also provided, largely to facilitate comparison with prior measurements. This data is of particular use for understanding the axial‐vector form factor of the nucleon as well as improving the simulation of low energy neutrino interactions on nuclear targets, which is of particular relevance for experiments searching for neutrino oscillations.
