从Yang-Mills规范理论预测普朗克尺度和牛顿常数:1圈和2圈估计

Predicting Planck scale and Newtonian constant from a Yang-Mills gauge theory: 1 and 2-loops estimates

Rodrigo F. Sobreiro, Anderson A. Tomaz

摘要:

最近,一个基于$SO(5)$ Yang-Mills作用量的Euclidian四维时空突现引力模型被提出。在这项工作中,我们提供了一些1和2循环计算,并表明该模型可以容纳适当的预测值的牛顿常数。此外,我们还证明了量子理论与几何动力学理论之间所期望的跃迁的典型尺度与普朗克尺度是一致的。我们还讨论了宇宙学常数问题。

英文摘要:

Recently, a model for an emergent gravity based on $SO(5)$ Yang-Mills action in Euclidian 4-dimensional spacetime was proposed. In this work we provide some 1 and 2-loops computations and show that the model can accommodate suitable predicting values for the Newtonian constant. Moreover, it is shown that the typical scale of the expected transition between the quantum and the geometrodynamical theory is consistent with Planck scale. We also provide a discussion on the cosmological constant problem.
