我们计算了在T2K近区探测器上测得的末态无介子激发事件的带电电流截面。所用的方法是量子动力学输运理论。作为基准,首先显示了在$^{12}$C和$^{16}$O上的电子包含截面的结果,然后与T2K合作在C$8$H$8$和H$2$O靶上测量的数据进行了详细的比较。研究发现,2p2h过程的贡献主要与后倾角有关;它们的理论不确定度在实验不确定度之内。然后重点讨论了一些事件,在这些事件中,企业最初被创建,但随后又被重新吸收。他们的贡献被发现在前角是必不可少的。
We calculate the charged current cross sections obtained at the T2K near detector for $\nu_\mu$-induced events without pions in the final state. The method used is quantum-kinetic transport theory. Results are shown first, as a benchmark, for electron inclusive cross sections on $^{12}$C and $^{16}$O to be followed with a detailed comparison with the data measured by the T2K collaboration on C$_8$H$_8$ and H$_2$O targets. The contribution of 2p2h processes is found to be relevant mostly for backwards angles; their theoretical uncertainties are within the experimental uncertainties. Particular emphasis is then put on a discussion of events in which pions are first created, but then reabsorbed. Their contribution is found to be essential at forward angles.
