标题： Missing matter in galaxies as a neutrino mixing effect

摘要： 我们证明，在弯曲时空中的量子场论框架下，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，并且在弱场近似下，证明味真空作为约化势的修正贡献给牛顿势。 这种修正的势可能解释螺旋星系的平坦旋转曲线。 从这个角度来看，中微子混合可能对暗物质有所贡献。 显示英文摘要

摘要： 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
