一旦暗物质被发现并确定了它的粒子物理性质,一个关键的问题就出现了,那就是它是如何在早期宇宙中产生的。如果它的热平均湮灭截面在几× 10−26 cm 3/s的范围内,那么在标准宇宙学场景(即辐射主导的宇宙)中的WIMP机制将是非常有利的。如果不是这种情况,我们可以考虑另一种产生机制,或者非标准宇宙学。在这里,我们研究了暗物质的生产方案与非标准的膨胀历史。此外,我们重建了可能的非标准宇宙学,可以使WIMP机制可行。
Once dark matter has been discovered and its particle physics properties have been determined, a crucial question rises concerning how it was produced in the early Universe. If its thermally averaged annihilation cross section is in the ballpark of few× 10−26 cm3/s, the WIMP mechanism in the standard cosmological scenario (i.e. radiation dominated Universe) will be highly favored. If this is not the case one can either consider an alternative production mechanism, or a non-standard cosmology. Here we study the dark matter production in scenarios with a non-standard expansion history. Additionally, we reconstruct the possible non-standard cosmologies that could make the WIMP mechanism viable.
