大质量和混合中微子的味破坏

On flavor violation for massive and mixed neutrinos

M. Blasone, A. Capolupo, C. R. Ji, G. Vitiello

摘要:

本文讨论了QFT中混合中微子的味荷和味态。我们表明,Pontecorvo态的味电荷的本征态。这意味着,它们在描述味中微子的使用产生违反轻子电荷守恒的生产/检测顶点。味荷本征态定义的味荷态给出了荷电弱相互作用过程中混合中微子的正确表示。

英文摘要:

We discuss flavor charges and states for interacting mixed neutrinos in QFT. We show that the Pontecorvo states are not eigenstates of the flavor charges. This implies that their use in describing the flavor neutrinos produces a violation of lepton charge conservation in the production/detection vertices. The flavor states defined as eigenstates of the flavor charges give the correct representation of mixed neutrinos in charged current weak interaction processes.
