论文摘要
包含电子中微子充电 - 电流横截面是在NOVA附近使用$ 8.02 \ times10^{20} $ protons-on-target(pot)的NOVA测量的。 GEV电子中微子相互作用的样本是迄今为止分析的最大分析,并受到$ \ simeq $ 17 \%系统的限制,而不是$ \ simeq $ 7.4 \%\%统计不确定性。在最终电子能量和角度中的双差横截面首次提出,以及对$ q^{2} $(平方四元转移)和能量的单差依赖性在1 GEV $ \ leqe_ν<$ 6 GEV的范围内。对精灵,Gibuu,Neut和Nuwro Neutrino事件发生器的预测进行了详细的比较。在测量的所有三个横截面中,数据并不比其他模型始终如一地偏爱模型,尽管某些模型在单个差分横截面中与$ q^{2} $中的一致性特别不好。
The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using $8.02\times10^{20}$ protons-on-target (POT) in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by $\simeq$ 17\% systematic rather than the $\simeq$ 7.4\% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on $Q^{2}$ (squared four-momentum transfer) and energy, in the range 1 GeV $ \leq E_ν < $6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs. $Q^{2}$.
