暗能量与暗物质、镜像世界与E_6统一

Dark Energy and Dark Matter, Mirror World and E_6 Unification

C. R. Das, L. V. Laperashvili

摘要:

在本演讲中,我们提出了平行的普通世界(O)和镜像世界(M)的概念。我们已经证明,在破镜宇称(MP)的情况下,在O-和M-世界的精细结构常数的演变是不相同的。假设超弦理论激发的E_6-统一在\sim 10^{18} GeV的尺度上恢复了破缺的MP,这必然导致在这个尺度上不同的E_6-破缺:在O-世界中是E_6 \to SO(10)\times U(1)_Z -,在M-世界中是E '_6 \to SU(6)' \times SU(2 ′_Z -.在只考虑渐近自由理论的情况下,我们给出了所有反规范常数α_i^{-1}在单圈近似下的运行。然后讨论了加速宇宙模型的一个“精髓”方案。这种情况与一个新规范群SU(2 π '_Z)的轴子(“加速子”)有关,该规范群的耦合常数g_Z在尺度Λ_Z \sim 10^{-3} eV处极端增长。

英文摘要:

In the present talk we have developed a concept of parallel ordinary (O) and mirror (M) worlds. We have shown that in the case of a broken mirror parity (MP), the evolutions of fine structure constants in the O- and M-worlds are not identical. It is assumed that E_6-unification inspired by superstring theory restores the broken MP at the scale \sim 10^{18} GeV, what unavoidably leads to the different E_6-breakdowns at this scale: E_6 \to SO(10)\times U(1)_Z - in the O-world, and E'_6 \to SU(6)'\times SU(2)'_Z - in the M-world. Considering only asymptotically free theories, we have presented the running of all the inverse gauge constants α_i^{-1} in the one-loop approximation. Then a `quintessence' scenario is discussed for the model of accelerating universe. Such a scenario is related with an axion (`acceleron') of a new gauge group SU(2)'_Z which has a coupling constant g_Z extremely growing at the scale Λ_Z\sim 10^{-3} eV.
