摘要

原则上，粒子物理学标准模型的一个最小扩展，即双希格斯双重态模型，可以用来解释造成暗能量的标量场。这两种孪生体一般是混合的。对角化后，最轻的cp -偶数希格斯粒子和cp -奇数希格斯粒子共同被认为是暗能量候选者。在这种情况下，从希格斯场获得的暗能量与宇宙常数无法区分。

The extra scalar degrees of freedom from the two Higgs doublet model for dark energy

In principle a minimal extension of the standard model of Particle Physics, the two Higgs doublet model, can be invoked to explain the scalar field responsible of dark energy. The two doublets are in general mixed. After diagonalization, the lightest CP-even Higgs and CP-odd Higgs are jointly taken to be the dark energy candidate. The dark energy obtained from Higgs fields in this case is indistinguishable from the cosmological constant.
