具有宇宙学破缺量子标度不变性的标准模型

Standard Model with Cosmologically Broken Quantum Scale Invariance

Pankaj Jain, Subhadip Mitra

摘要:

我们认为尺度不变性在量子场论中并不是反常的,只要它在宇宙学上被打破。我们考虑粒子物理学的标准模型的局部尺度不变的扩展,并认为它适合粒子和宇宙学观测。该模型是经典和量子力学尺度不变。尺度不变性在宇宙学上被打破,产生了所有的维度参数。宇宙学常数或暗能量是理论的预测,可以在微扰论中逐阶系统地计算。预计在所有订单上都是有限的。该模型不受层次问题,由于缺乏标量粒子,包括希格斯粒子,从物理光谱。

英文摘要:

We argue that scale invariance is not anomalous in quantum field theory, provided it is broken cosmologically. We consider a locally scale invariant extension of the Standard Model of particle physics and argue that it fits both the particle and cosmological observations. The model is scale invariant both classically and quantum mechanically. The scale invariance is broken cosmologically producing all the dimensionful parameters. The cosmological constant or dark energy is a prediction of the theory and can be calculated systematically order by order in perturbation theory. It is expected to be finite at all orders. The model does not suffer from the hierarchy problem due to absence of scalar particles, including the Higgs, from the physical spectrum.
