加速质子β衰变和中微子振荡:具有CP破坏的三味描述

On the beta-decay of the accelerated proton and neutrino oscillations: a three-flavor description with CP violation

Massimo Blasone, Gaetano Lambiase, Giuseppe Gaetano Luciano, Luciano Petruzziello

摘要:

在双味中微子混合和振荡的背景下,研究了匀加速质子(p -> n + e+ + ne)的(逆)β衰变。已经证明,由惯性和随动观测者测量的衰变率是一致的,条件是:i)考虑加速真空的热性质(Unruh效应); ii)中微子的渐近行为是通过味(而不是质量)本征态描述的; iii)Unruh辐射是由振荡中微子组成的。在这里,我们将上述考虑扩展到一个更现实的情况下,包括三代狄拉克中微子。通过遵循概述的配方,我们发现两个速率之间的相等仍然成立,证实了混合与量子场论的广义协方差完全一致。值得注意的是,我们证明了在中微子振荡CP破坏的分析提供了一个进一步的坚实的论据味态作为基本的渐近中微子状态的表示。我们的方法进行了讨论,最后与文献中出现的其他治疗方法进行了比较。

英文摘要:

The (inverse) beta-decay of uniformly accelerated protons (p -> n + e+ + ne) has been recently analyzed in the context of two-flavor neutrino mixing and oscillations. It has been shown that the decay rates as measured by an inertial and comoving observer are in agreement, provided that: i) the thermal nature of the accelerated vacuum (Unruh effect) is taken into account; ii) the asymptotic behavior of neutrinos is described through flavor (rather than mass) eigenstates; iii) the Unruh radiation is made up of oscillating neutrinos. Here we extend the above considerations to a more realistic scenario including three generations of Dirac neutrinos. By following the outlined recipe, we find that the equality between the two rates still holds true, confirming that mixing is perfectly consistent with the General Covariance of Quantum Field Theory. Notably, we prove that the analysis of CP violation in neutrino oscillations provides a further solid argument for flavor states as fundamental representation of asymptotic neutrino states. Our approach is finally discussed in comparison with the other treatments appeared in literature.
