Brans-Dicke宇宙学中的费米子

Fermions in Brans-Dicke cosmology

L. L. Samojeden, F. P. Devecchi, G. M. Kremer

摘要:

利用Brans-Dicke引力理论,我们研究了一个充满费米子场(具有自相互作用势)和由正压状态方程控制的物质组分的假设宇宙。结果表明,费米子场(与Brans-Dicke标量场相结合)可能是负责最后的加速时代后,最初的物质占主导地位的时期。

英文摘要:

Using the Brans-Dicke theory of gravitation we put under investigation a hypothetical universe filled with a fermionic field (with a self interaction potential) and a matter constituent ruled by a barotropic equation of state. It is shown that the fermionic field (in combination with the Brans-Dicke scalar field) could be responsible for a final accelerated era, after an initial matter dominated period.
