Since several years the phenomenon of neutrino oscillations is intensively studied. It describes the change of different flavors of neutrinos, which are electrical neutral particles that participate only in weak interactions. One leading experiment here is the T2K experiment. It found for the first time indications for a difference between the oscillations of neutrinos and anti-neutrinos. This difference, which in particle physics is called CP violation, could be an explanation for the disappearance of anti-matter after the big bang. The proposed experiment T2K-II will improve the current measurements and will try to find evidence for CP violation in the leptonic sector, where neutrinos belong to.

近几年来，中微子振荡现象得到了广泛的研究。它描述了中微子的不同口味的变化，中微子是电中性粒子，只参与弱相互作用。其中一个主要的实验是T2 K实验。它首次发现了中微子和反中微子振荡之间差异的迹象。这种差异，在粒子物理学中被称为CP破坏，可以解释大爆炸后反物质的消失。拟议中的实验T2 K-II将改善目前的测量，并将试图在中微子所属的轻子区找到CP破坏的证据。
