二次引力的物理内容

Physical content of Quadratic Gravity

Enrique Alvarez, Jesus Anero, Sergio Gonzalez-Martin, Raquel Santos-Garcia

摘要:

我们最近经历了一个分析的引力理论定义在一阶形式主义,度量和连接被视为独立的领域。连接场的物理意义在历史上一直有些难以捉摸。在本文中,一个完整的自旋分析的无挠连接场进行,并探讨其后果。讨论了该理论的假设一致截断的主要性质。

英文摘要:

We have recently undergone an analysis of gravitational theories as defined in first order formalism, where the metric and the connection are treated as independent fields. The physical meaning of the connection field has historically been somewhat elusive. In this paper, a complete spin analysis of the torsionless connection field is performed, and its consequences are explored. The main properties of a hypothetical consistent truncation of the theory are discussed as well.
