论文摘要
这项研究为区分动力学和静态暗能量而制定了新的工具。它提供了动态宇宙学参数和基本常数的准确进化模板,作为量表因子的分析函数。它们旨在基于特定动力学宇宙学和暗能电位的物理学来代替可能性计算中常用的参数化。因此,它们被称为宇宙学和潜在的特异性CPS,模板。计算了一套CPS模板的套件,该模板是针对具有与希格斯电位相同数学形式的暗能电位的平坦典型宇宙学。与大多数单一电位不同,这种Higgs启发了HI,多项式电势会产生丰富的演变。该研究产生的CPS模板是量表因子的分析功能。它使用了最近开发的beta函数形式主义,该形式主义为标量因子提供了标量的差异功能。这建立了一种方法,用于轻松生产其他黑暗能量电位和宇宙学的CPS模板,以确定相对于Lambda CDM的动力宇宙学的可能性。该研究还研究了基本常数(例如质子与电子质量比)以及涉及粒子物理与宇宙学之间相交的精细结构常数的演变。附录A显示了一套删节的CPS模板套件,以实现平坦的精髓和HI暗能电位。
This study forges new tools to discriminate between dynamical and static dark energy. It provides accurate evolutionary templates of dynamical cosmological parameters and fundamental constants as analytic functions of the scale factor. They are designed to replace the commonly used parameterizations in likelihood calculations with evolutionary templates based on the physics of specific dynamical cosmologies and dark energy potentials. Thus they are termed Cosmology and Potential Specific, CPS, templates. A suite of CPS templates are calculated for a flat quintessence cosmology with a dark energy potential of the same mathematical form as the Higgs potential. This Higgs inspired, HI, polynomial potential produces a rich set of evolutions unlike most monomial potentials. The study produces CPS templates that are analytic functions of the scale factor. It uses a recently developed beta function formalism that provides a differential function for the scalar in terms of the scale factor. This establishes a methodology for easily producing CPS templates for other dark energy potentials and cosmologies to determine the likelihoods of dynamical cosmologies relative to Lambda CDM. The study also examines the evolution of fundamental constants such as the proton to electron mass ratio and the fine structure constant involving an intersection between particle physics and cosmology. Appendix A displays an abridged suite of CPS templates for flat quintessence and the HI dark energy potential.
