摘要

本文概述了当使用标准模型扩展(SME)来研究具有显式微分同态破缺的引力理论时会发生什么。结果表明，当考虑物质-重力耦合时，SME通常与Bianchi恒等式保持一致，因此它为研究重力理论中显式微分同态破缺的影响提供了一个有用的现象学框架。

The SME with Gravity and Explicit Diffeomorphism Breaking

This overview looks at what happens when the Standard-Model Extension (SME) is used to investigate gravity theories with explicit diffeomorphism breaking. It is shown that when matter-gravity couplings are included, the SME generally maintains consistency with the Bianchi identities, and it therefore provides a useful phenomenological framework for investigating the effects of explicit diffeomorphism breaking in gravity theories.
