生长物质

Growing Matter

Luca Amendola, Marco Baldi, Christof Wetterich

摘要:

我们调查的精髓宇宙学的物质组成部分组成的粒子质量不断增加。虽然在早期宇宙学中可以忽略不计,但不断增长的物质成分的出现阻止了宇宙子场的演化,使其红移约为6。反过来,这又引发了宇宙的加速膨胀。我们建议把成长中的物质与中微子联系起来。然后由中微子质量确定了目前观测到的暗能量密度及其状态方程。

英文摘要:

We investigate quintessence cosmologies with a matter component consisting of particles with an increasing mass. While negligible in early cosmology, the appearance of a growing matter component has stopped the evolution of the cosmon field at a redshift around six. In turn, this has triggered the accelerated expansion of the Universe. We propose to associate growing matter with neutrinos. Then the presently observed dark energy density and its equation of state are determined by the neutrino mass.
