费米子引力重子生成的不稳定性

Instability of gravitational baryogenesis with fermions

E. V. Arbuzova, A. D. Dolgov

摘要:

在引力重子生成方案中,重子流与曲率标量的导数耦合导致了引力场的高阶方程。结果表明,这些方程是强不稳定的,破坏了标准宇宙学。这是我们以前从标量重子到实际费米子的结果的推广。

英文摘要:

The derivative coupling of baryonic current to the curvature scalar in gravitational baryogenesis scenarios leads to higher order equations for gravitational field. It is shown that these equations are strongly unstable and destroy standard cosmology. This is a generalization of our earlier results obtained for scalar baryons to realistic fermions.
