暗能量与暗物质之间耦合常数的约束条件

Constraints on coupling constant between dark energy and dark matter

Mubasher Jamil, Muneer Ahmad Rashid

摘要:

我们研究了暗物质和相互作用的Chaubergin气体之间的耦合约束。我们的研究结果表明,这两个实体之间的耦合常数$c$可以采取任意值,可以是正的或负的,从而给任意自由Chaobergin气体和暗物质之间的相互转换。因此,我们的结果表明,限制$0<c<1$的耦合常数,发生作为一个非常特殊的情况。我们的分析也支持在一定条件下的耦合常数的幻影能量的存在。

英文摘要:

We have investigated constraints on the coupling between dark matter and the interacting Chaplygin gas. Our results indicate that the coupling constant $c$ between these two entities can take arbitrary values, which can be either positive or negative, thus giving arbitrary freedom to the inter-conversion between Chaplygin gas and dark matter. Thus our results indicate that the restriction $0<c<1$ on the coupling constant occurs as a very special case. Our analysis also supports the existence of phantom energy under certain conditions on the coupling constant.
