摘要

我们证明了在弯曲时空量子场论的框架下，中微子味真空的半经典能量动量张量满足尘埃和冷暗物质的状态方程。我们考虑球对称时空，并且我们证明，在弱场近似中，风味真空对牛顿势的汤川修正有贡献。这个修正后的势能可以解释螺旋星系的平坦旋转曲线。从这个角度来看，中微子的混合可能有助于暗物质的形成。

Missing matter in galaxies as a neutrino mixing effect

We show that, in the framework of quantum field theory in curved spacetime, the semiclassical energy–momentum tensor of the neutrino flavor vacuum fulfills the equation of state of dust and cold dark matter. We consider spherically symmetric spacetimes, and we demonstrate that, within the weak field approximation, the flavor vacuum contributes as a Yukawa correction to the Newtonian potential. This corrected potential may account for the flat rotation curves of spiral galaxies. In this perspective, neutrino mixing could contribute to dark matter.
