论文摘要
我们研究混合中微子的狄拉克方程的非相关性极限。我们证明，这种程序不可避免地导致惯性质量的重新定义。发生这种情况是因为与没有混合的情况相反，反粒子部门的贡献不能忽略具有确定风味的中微子。然后，我们表明，当重力相互作用被打开时，在弱场近似中，将质量参数与重力（重力质量）并不与惯性质量相同，从而导致弱等价原则的明显崩溃。
We study the non-relativistic limit of Dirac equation for mixed neutrinos. We demonstrate that such a procedure inevitably leads to a redefinition of the inertial mass. This happens because, in contrast to the case when mixing is absent, the antiparticle sector contribution cannot be neglected for neutrinos with definite flavor. We then show that, when a gravitational interaction is switched on, in the weak-field approximation the mass parameter which couples to gravity (gravitational mass) does not undergo the same reformulation as the inertial mass, thus leading to an apparent breakdown of the weak equivalence principle.
