摘要:

分析了MiniBooNE实验收集的带电μ子中微子散射事件的高统计样本,以提取碳上带电准弹性(CCQE)散射的双微分截面($\frac{d^2σ}{dT_μd\cosθ_μ}$)的第一个测量值。该结果具有极小模型依赖性,并提供了迄今为止关于该过程的最完整信息。在CCQE散射的假设下,提取了作为中微子能量函数的绝对截面($σ[E_ν]$)和单微分截面($\frac{dσ}{dQ^2}$),以便与以前的测量结果进行比较.这些量可以用来表征核子的有效轴向矢量形状因子,并改进低能中微子与核靶相互作用的模拟。这一结果对寻找中微子振荡的实验有一定的参考价值。

英文摘要:

A high-statistics sample of charged-current muon neutrino scattering events collected with the MiniBooNE experiment is analyzed to extract the first measurement of the double differential cross section ($\frac{d^2σ}{dT_μd\cosθ_μ}$) for charged-current quasielastic (CCQE) scattering on carbon. This result features minimal model dependence and provides the most complete information on this process to date. With the assumption of CCQE scattering, the absolute cross section as a function of neutrino energy ($σ[E_ν]$) and the single differential cross section ($\frac{dσ}{dQ^2}$) are extracted to facilitate comparison with previous measurements. These quantities may be used to characterize an effective axial-vector form factor of the nucleon and to improve the modeling of low-energy neutrino interactions on nuclear targets. The results are relevant for experiments searching for neutrino oscillations.
