In contrast to internal symmetries, there is no general proof that the coset construction for spontaneously broken spacetime symmetries leads to universal dynamics. One key differe…

Higher Derivative Field Theories: Degeneracy Conditions and Classes
Marco Crisostomi, Remko Klein, Diederik Roest
We provide a full analysis of ghost free higher derivative field theories with coupled degrees of freedom. Assuming the absence of gauge symmetries, we derive the degeneracy condit…
