MiniBooNE荷电准弹性反中微子数据的新结果

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

Joseph Grange

摘要:

MiniBooNE反中微子带电电流准弹性(CCQE)的数据进行比较模型的预测。中微子引起的事件的主要背景检查第一,其中三个独立的技术。结果表明,中微子通量是一致的$\sim$ 20%的相对于很大程度上不确定的预测统一减少。扣除背景后,$\numub$ CCQE事件的$Q^{2}$形状与根据MiniBooNE $\numu$ CCQE数据确定的模型参数$M_{A}$ = 1.35 GeV一致,而归一化比相同预测高$\sim$ 20%。

英文摘要:

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 $\numub$ CCQE events is consistent with the model parameter $M_{A}$ = 1.35 GeV determined from MiniBooNE $\numu$ CCQE data, while the normalization is $\sim$ 20% high compared to the same prediction.
