宇宙学与标准模型的非对易方法

Cosmology and the Noncommutative approach to the Standard Model

William Nelson, Mairi Sakellariadou

摘要:

我们研究了标准模型的非对易方法的宇宙学后果。忽略希格斯场与曲率的非最小耦合,爱因斯坦方程的非对易修正只存在于非均匀和各向异性的时空中。然而,考虑到名义耦合,我们甚至得到背景宇宙学的修正。一个链接与电子引力以及变色龙宇宙学进行了简要讨论,并提到潜在的实验后果。

英文摘要:

We study cosmological consequences of the noncommutative approach to the standard model. Neglecting the nonminimal coupling of the Higgs field to the curvature, noncommutative corrections to Einstein's equations are present only for inhomogeneous and anisotropic space-times. Considering the nominimal coupling however, we obtain corrections even for background cosmologies. A link with dilatonic gravity as well as chameleon cosmology are briefly discussed, and potential experimental consequences are mentioned.
