局部洛仑兹不变性与一个等价于广义相对论的新引力理论

Local Lorentz invariance and a new theory of gravitation equivalent to General Relativity

C. Wiesendanger

摘要:

本文发展了一个质量维一维规范场与任意自旋物质耦合的洛仑兹群的规范理论。作为一个全新的功能,“维尔拜因”确保当地的规范不变性进入不是作为一个独立的动力场,但出现作为一个功能的洛伦兹规范场。这个理论的基本几何是一个$SO(1,3)$ Banach丛。用规范场及其一阶导数构造了最一般的作用量,它可以通过幂次计数重正化。它不包含规范场的高阶导数项,而高阶导数项会破坏通常的可重整化引力$R^2$理论中的么正性。最后建立了耦合到自旋零物质的Lorentz规范场理论与广义相对论的等价性

英文摘要:

A gauge theory of the Lorentz group with a mass-dimension one gauge field coupling to matter of any spin is developed. As a completely new feature the "Vierbein" assuring local gauge invariance enters not as an independent dynamical field, but emerges as a functional of the Lorentz gauge field. The underlying geometry of the theory turns out to be a $SO(1,3)$ Banach bundle. The most general action which is renormalizable by power-counting is constructed in terms of the gauge field and its first derivatives. It contains no higher derivative terms in the gauge field which destroy unitarity in the usual renormalizable $R^2$-theories of gravitation. Finally equivalence of the Lorentz gauge field theory coupled to spin zero matter with General Relativity is established
