论文摘要
引入了两体电流(2p2h)对中微子横截面的贡献的现象学模型。使用T2K和Minerva实验的CC0PI测量结果对Valencia模型的2P2H进行预测。我们的结果表明,在大于1 GEV的中微子能量下,2P2H横截面的显着增加,以及2P2H事件的重新分布是能量和动量传递的功能。这可能会对中微子振荡参数中的中微子能量重建产生重大影响。
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.
