弦启发解释我们宇宙的超加速
String inspired explanation for the super-acceleration of our universe
摘要：
我们研究了一般Gauss-Bonnet膜世界中的体含量对宇宙演化的影响。我们发现，高斯-邦纳项和暗辐射与体块物质含量的结合在宇宙演化中起着至关重要的作用。我们证明了我们的模型可以用与观测一致的有效暗能量状态方程来描述宇宙的超加速。
英文摘要：
We investigate the effect of the bulk content in the general Gauss-Bonnet braneworld on the evolution of the universe. We find that the Gauss-Bonnet term and the combination of the dark radiation and the matter content of the bulk play a crucial role in the universe evolution. We show that our model can describe the super-acceleration of our universe with the equation of state of the effective dark energy in agreement with observations.
