引力子的质量可以用具有四个标量场的Brout-Engert-Higgs机制产生。我们证明，当这些场中的一个像在模拟引力中那样被共约束时，得到的质量引力是无鬼影的和一致的。质量项不是Fierz-Pauli类型的。只有五个自由度，而与Boulware-Deser幽灵相关的第六个自由度受到限制，并被所有顺序的模拟物质所取代。范·达姆-维尔特曼-扎哈罗夫间断也不存在。
A bstractThe mass of the graviton can be generated using a Brout-Englert-Higgs mechanism with four scalar fields. We show that when one of these fields is costrained as in mimetic gravity, the massive gravity obtained is ghost free and consistent. The mass term is not of the Fierz-Pauli type. There are only five degrees of freedom and the sixth degree of freedom associated with the Boulware-Deser ghost is constrained and replaced by mimetic matter to all orders. The van Dam-Veltman-Zakharov discontinuity is also absent.
