Massive Gravity in Minkowski Space via Gravitational Higgs Mechanism
arXiv:0710.1061 · doi:10.1103/PhysRevD.77.024001
Abstract
In gravitational Higgs mechanism graviton components acquire mass in the process of spontaneous breaking of diffeomorphisms (via scalar vacuum expectation values). Recently, gravitational Higgs mechanism was discussed in the context of obtaining massive gravity directly in four dimensions. We discuss a setup, with all diffeomorphisms spontaneously broken by scalars, where gravitational Higgs mechanism results in massive gravity in Minkowski space with no non-unitary propagating modes. This is achieved by including higher derivative terms in the scalar sector. Decoupling the non-unitary mode (trace of the graviton) then requires tuning a single parameter, namely, the cosmological constant. We also discuss a setup where only spatial diffeomorphisms are broken. In this case we obtain massive gravity in Minkowski space with only transverse modes propagating, so the mode count is the same as for a massless graviton.
