本文报道了在T2 K离轴近探测器上用质子靶测量碳上μ介子中微子荷电流与末态单个正电荷π介子相互作用的单微分截面和双微分截面。该分析使用用于背景减除的数据对照样品，并且使用展开方法提取截面信号，截面信号被定义为从目标核离开的单个带负电荷的μ介子和单个带正电荷的π介子。在峰值为0.6GeV的T2 K离轴中微子束谱上积分得到的模型相关截面为σ=（11.76±0.44（stat）±2.39（syst））×10-40 cm ~ 2核子~（-1）。测量了各种微分截面，包括中微子与重核靶相互作用中产生单电荷π介子的阿德勒角的首次测量。
We report the measurements of the single and double differential cross section of muon neutrino charged-current interactions on carbon with a single positively charged pion in the final state at the T2K off-axis near detector usingprotons on target. The analysis uses data control samples for the background subtraction and the cross section signal, defined as a single negatively charged muon and a single positively charged pion exiting from the target nucleus, is extracted using an unfolding method. The model-dependent cross section, integrated over the T2K off-axis neutrino beam spectrum peaking at 0.6 GeV, is measured to be σ=(11.76±0.44(stat)±2.39(syst))×10-40 cm2 nucleon-1. Various differential cross sections are measured, including the first measurement of the Adler angles for single charged pion production in neutrino interactions with heavy nuclei target.
