摘要:

我们计算的带电电流截面在T2 K离轴附近的探测器$ν_μ$诱导的事件没有π介子和任何数量的质子在最终状态下使用传输理论编码的GiBUU模型。在与最近的T2 K数据的比较中,确定了2 p2 h多核子相关性的强度。将其与初始核态的同位旋(T)联系起来,发现T=0导致最近由T2 K得到的截面的拟合明显更好,从而实现了电子-核反应和中微子-核反应之间2 p2 h多核子关联贡献的一致性。

英文摘要:

We calculate the charged-current cross sections obtained at the T2K off-axis near detector for $ν_μ$-induced events without pions and any number of protons in the final state using transport theory as encoded in the GiBUU model. In a comparison with recent T2K data the strength of the 2p2h multinucleon correlations is determined. Linking this to the isospin (T) of the initial nuclear state, it is found that T=0 leads to a significantly better fit of the recent cross sections obtained by T2K, thus achieving consistency of the 2p2h multi-nucleon correlation contributions between electron-nucleus and neutrino-nucleus reactions.
