宇宙学标量场与大爆炸核合成

Cosmological scalar fields and Big-Bang nucleosynthesis

A. Arbey, J. -F. Coupechoux

摘要:

标量场被广泛用于宇宙学,特别是模拟暗能量,例如在精粹模型中,或解释暗物质,特别是在模糊暗物质模型中。此外,许多涉及原始标量场的场景,可能已经驱动了暴胀或重子生成,目前正在审查中。在这篇文章中,我们研究了这种标量场对大爆炸核合成的影响,并利用观测到的元素丰度导出了对它们参数的约束。

英文摘要:

Scalar fields are widely used in cosmology, in particular to emulate dark energy, for example in quintessence models, or to explain dark matter, in particular within the fuzzy dark matter model. In addition many scenarios involving primordial scalar fields which could have driven inflation or baryogenesis are currently under scrutiny. In this article, we study the impact of such scalar fields on Big-Bang nucleosynthesis and derive constraints on their parameters using the observed abundance of the elements.
