本文首次联合测量了T2K实验中烃类在离轴附近的中微子、中微子和反中微子的双微分中微子和无中子态荷电截面。本文分析的数据包括中微子模式和反中微子模式下的质子入射到靶上，束流能量峰值为0.6GeV。利用两个测量的截面，计算了总和、差值和不对称性，目的是更好地理解这种相互作用中所涉及的核效应。将提取的测量结果与不同蒙特卡罗产生器和理论模型的预测进行了比较，表明两个截面之间的差异对核效应具有有趣的敏感性。
This paper presents the first combined measurement of the double-differential muon neutrino and antineutrino charged-current cross sections with no pions in the final state on hydrocarbon at the off-axis near detector of the T2K experiment. The data analyzed in this work compriseandprotons on target in neutrino and antineutrino mode respectively, at a beam energy peak of 0.6 GeV. Using the two measured cross sections, the sum, difference, and asymmetry were calculated with the aim of better understanding the nuclear effects involved in such interactions. The extracted measurements have been compared with the prediction from different Monte Carlo generators and theoretical models showing that the difference between the two cross sections have interesting sensitivity to nuclear effects.
