Abstract
The largest sample ever recorded of ν̅ [subscript μ] charged-current quasielastic (CCQE, ν̅ [subscript μ]+p→μ[superscript +]+n) candidate events is used to produce the minimally model-dependent, flux-integrated double-differential cross section d[superscript 2]σ/dT[subscript μ]dcosθ[subscript μ] for ν̅ [subscript μ] CCQE for a mineral oil target. This measurement exploits the large statistics of the MiniBooNE antineutrino mode sample and provides the most complete information of this process to date. In order to facilitate historical comparisons, the flux-unfolded total cross section σ(E[subscript ν]) and single-differential cross section dσ/dQ[superscript 2] on both mineral oil and on carbon are also reported. The observed cross section is somewhat higher than the predicted cross section from a model assuming independently acting nucleons in carbon with canonical form factor values. The shape of the data are also discrepant with this model. These results have implications for intranuclear processes and can help constrain signal and background processes for future neutrino oscillation measurements.
