Grange, Joseph

MiniBooNE anti-neutrino charged-current quasi-elastic (CCQE) data is compared to model predictions. The main background of neutrino-induced events is examined first, where three independent techniques are employed. Results indicate the neutrino flux is consistent with a uniform reduction of {approx}20% relative to the largely uncertain prediction. After background subtraction, the Q{sup 2} shape of {bar v}{sub {mu}} CCQE events is consistent with the model parameter MA = 1.35 GeV determined from MiniBooNE v{sub {mu}} CCQE data, while the normalization is {approx} 20% high compared to the same prediction.
