我们利用GiBUU模型中编码的输运理论,计算了在T2K离轴附近探测器处无介子和任意数目质子的末态诱导事件的带电电流截面。通过与最近的T2K数据的比较,确定了2p2小时多核子关联的强度。将其与初始核态的同位旋(T)联系起来,发现T=0使T2K得到的最新截面有明显的更好的拟合度,从而实现了电子-核和中微子-核反应之间2p2小时多核子关联贡献的一致性。
We calculate the charged-current cross sections obtained at the T2K off-axis near detector for $\nu_\mu$-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.
