欧洲核子研究的科学家对中性 K介子的衰变特征进行了迄今精度最高的观测 ,进一步直接确认了“电荷宇称不守恒”现象的存在 .早先的理论认为 ,物理定律在空间反射的情况下是不变的 ,这被称为“宇称守恒”.宇称守恒可以简单理解为 ,基本粒子在照镜子时 ,其镜中的像与粒子具有对称 Scientists at the European Nuclear Research Institute have performed the highest accuracy observations of the decay characteristics of the neutral K meson so far, and have further directly confirmed the existence of the “charge parity parity non-conservation” phenomenon. Earlier theories believed that the physical laws were in the case of spatial reflections. Invariant, this is called “conservation of parity.” Parity conservation can be simply understood as that when the elementary particles are in the mirror, the images in the mirror are symmetrical with the particles.
