初始条件对小Higgs模型下暗物质残留密度影响的研究

Effect of Initial Conditions vs Residual Density of Littlest Higgs Model Dark Matter

利用玻尔兹曼方程把演化的初始条件对重光子在当前宇宙中的残留密度的影响进行了系统的研究.结果表明,初始条件仅对宇宙演化的初期有着较小影响,但对当前宇宙中暗物质的残留密度的影响几乎可以忽略.

Using the Boltzmann equation to study the effect of the initial conditions vs residual density of Little Higgs Model Dark matter systematically.The results show that the initial conditions only affect the early evolution of the universe slightly and don＇t affect the currently residual density of dark matter.
