摘要:

介绍了一个两体电流(2 p ~ 2 h)对中微子截面贡献的唯象模型。瓦伦西亚模型的预测2 p2 h修改使用最近的CC 0 pi测量T2 K和MINERvA实验。我们的结果表明,在中微子能量大于1 GeV的2 p2 h截面的显着增加,也是一个重新分配的2 p2 h事件的功能的能量和动量转移。这可能对中微子振荡参数中的中微子能量重构产生很大影响。

英文摘要:

A phenomenological model of two-body current (2p2h) contribution to neutrino cross section is introduced. Predictions of the Valencia model for 2p2h are modified using recent CC0pi measurements from T2K and MINERvA experiments. Our results suggest a significant increase of the 2p2h cross section at neutrino energies bigger than 1 GeV and also a redistribution of 2p2h events as function of energy and momentum transfer. This may have a big impact on neutrino energy reconstruction in neutrino oscillation parameters.
