异常加权能量假说:暗物质与暗能量之间缺失的环节

The Abnormally Weighting Energy Hypothesis: the Missing Link between Dark Matter and Dark Energy

J. -M. Alimi, A. Füzfa

摘要:

通过引入一种反常加权型能量,我们推广了引力张量-标量理论。这个张量-标量反常引力理论是基于弱等效原理的放松,现在仅限于普通可见物质。因此,向广义相对论的收敛机制被修改,并自然产生宇宙加速度,作为由某些不可见扇区的质量变化引起的不可避免的引力反馈。这个新的理论框架的宇宙学意义进行了研究。从哈勃图宇宙学测试\textit{alone},这个理论提供了一个估计的重子和暗物质在宇宙中的数量是一致的宇宙微波背景(CMB)和大爆炸核合成(BBN)的独立宇宙学测试。宇宙的巧合是从一个同样自然的假设标量耦合强度的振幅自然实现。最后,从超新星数据的充分性出发,我们导出了引力耦合的时空依赖性与暗物质质量之间的一个新的有趣关系,为宇宙学对微观物理的重要约束提供了一个例子。这让我们瞥见了可见和不可见部分之间诱人的新对称性,即可见和不可见物质的标量电荷正好相反。

英文摘要:

We generalize tensor-scalar theories of gravitation by the introduction of an abnormally weighting type of energy. This theory of tensor-scalar anomalous gravity is based on a relaxation of the weak equivalence principle that is now restricted to ordinary visible matter only. As a consequence, the convergence mechanism toward general relativity is modified and produces naturally cosmic acceleration as an inescapable gravitational feedback induced by the mass-variation of some invisible sector. The cosmological implications of this new theoretical framework are studied. From the Hubble diagram cosmological test \textit{alone}, this theory provides an estimation of the amount of baryons and dark matter in the Universe that is consistent with the independent cosmological tests of Cosmic Microwave Background (CMB) and Big Bang Nucleosynthesis (BBN). Cosmic coincidence is naturally achieved from a equally natural assumption on the amplitude of the scalar coupling strength. Finally, from the adequacy to supernovae data, we derive a new intriguing relation between the space-time dependences of the gravitational coupling and the dark matter mass, providing an example of crucial constraint on microphysics from cosmology. This glimpses at an enticing new symmetry between the visible and invisible sectors, namely that the scalar charges of visible and invisible matter are exactly opposite.
