New Results from MiniBooNE Charged-Current Quasi-Elastic Anti-Neutrino Data


Abstract in English

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 $sim$ 20% relative to the largely uncertain prediction. After background subtraction, the $Q^{2}$ shape of $ umub$ CCQE events is consistent with the model parameter $M_{A}$ = 1.35 GeV determined from MiniBooNE $ umu$ CCQE data, while the normalization is $sim$ 20% high compared to the same prediction.
