我们报道了费米实验室NuMI中微子束中MINERvA实验的分段闪烁体内跟踪器中ν（μ）荷电准弹性事件的研究。通过要求μ-和低热反冲能与相互作用顶点分离来选择事件。我们测量了通量平均微分截面dσ/dQ²，并研究了末态的低能粒子含量。在测量的dσ/dQ²和相对论费米气体中独立核子模型的期望值之间发现了偏差。我们还观察到一个多余的能量附近的顶点一致的多个质子在最后的状态。
We report a study of ν(μ) charged-current quasielastic events in the segmented scintillator inner tracker of the MINERvA experiment running in the NuMI neutrino beam at Fermilab. The events were selected by requiring a μ- and low calorimetric recoil energy separated from the interaction vertex. We measure the flux-averaged differential cross section, dσ/dQ², and study the low energy particle content of the final state. Deviations are found between the measured dσ/dQ² and the expectations of a model of independent nucleons in a relativistic Fermi gas. We also observe an excess of energy near the vertex consistent with multiple protons in the final state.
