标题： A Cosmological Reconstruction of the Higgs Vacuum Expectation Value

摘要： 我们提出了一种简单的玩具模型，该模型完全由嵌入大统一理论中的自相互作用标量场驱动宇宙加速。 标量的自相互作用类似于希格斯相互作用，并引发自发对称性破缺。 自相互作用势中二次项的系数具有演化特性，这导致质子与电子质量比 $\mu$ 的宇宙变化。 我们从运动学参数jerk进行宇宙重建，并讨论了该理论的一些宇宙学后果。 我们还比较了理论上计算的 $\mu$ 变化与铯原子钟数据中分子吸收光谱观测值。 显示英文摘要

摘要： We present a simple toy model of cosmic acceleration driven purely by a self-interacting scalar field embedded in theory of grand unification. The scalar self-interaction is Higgs-like and provokes a spontaneous symmetry breaking. The coefficient of the quadratic term in the self-interaction potential has an evolution and it leads to a cosmic variation of proton-to-electron mass ratio, $\mu$. We perform a cosmological reconstruction from the kinematic parameter jerk and discuss a few cosmological consequences of the theory. We also compare the theoretically calculated $\mu$ variation with the observations of molecular absorption spectra from Cesium Atomic Clock data.
