从宇宙学观点看暗能量和光WIMP暗物质

Dark energy and light WIMP dark matter from the cosmological viewpoint

V. E. Kuzmichev, V. V. Kuzmichev

摘要:

本文从重子、暗物质和暗能量密度对宇宙总物质-能量密度收支的贡献的天体物理数据中,给出了轻暗物质粒子和暗能量准粒子的质量估计。我们使用的量子宇宙学模型中,暗能量是一个凝聚的原始标量场的量子振荡。质量约为15 GeV的暗能量准粒子与7年WMAP和其他数据一致。准粒子可以通过破坏CP不变性衰变为重子、轻子和暗物质。WIMP的质量约为5 GeV,对应于重子和暗物质能量密度的观测值。这样的质量与CoGeNT、DAMA和CDMS的观测结果一致。暗能量的准粒子可以被记录为频率为~ 3.64 x 10^{24} 1/s的恒定辐射背景。暗物质粒子必须以信号的形式表现出来,其频率约为1.21 x 10^{24} 1/s,来自星系团的辐射,其中存在由暗物质产生的强烈引力场。

英文摘要:

We give an estimation of the masses of light dark matter particle and dark energy quasiparticle which can be extracted from the astrophysical data about the contributions of baryon, dark matter, and dark energy densities to the total matter-energy density budget in our universe. We use the quantum cosmological model in which dark energy is a condensate of quantum oscillations of primordial scalar field. The dark energy quasiparticle with the mass ~ 15 GeV is consistent with the 7-year WMAP and other data. The quasiparticles can decay with violation of CP-invariance into baryons, leptons, and dark matter. The WIMP mass ~ 5 GeV corresponds to observed values of baryon and dark matter energy densities. Such a mass agrees with the observations of CoGeNT, DAMA, and CDMS. Quasiparticles of dark energy can be registered as a constant background of radiation with the frequency ~ 3.64 x 10^{24} 1/s. Dark matter particles must exhibit themselves in the form of signals with the frequency ~ 1.21 x 10^{24} 1/s of radiation from galaxy clusters where the intensive gravitational fields produced by dark matter exist.
