Spontaneous symmetry breaking in models with second-class constraints
CA Escobar, R Linares - Physical Review D, 2022 - APS
In this work the spontaneous symmetry breaking in certain nonlinear theories with second-
class constraints is explored. Using the Dirac's method we perform an analysis of the …

Reconciling absence of vDVZ discontinuity with absence of ghosts in nonlocal linearized gravity
D Dalmazi - Classical and Quantum Gravity, 2023 - iopscience.iop.org
The modern massive gravity theories resolve a historical tension between the absence of
the so called vDVZ mass discontinuity and the absence of ghosts via a fine tuned …

Mass spectrum and linear perturbations of ghost-free multi-spin-2 theory
J Flinckman, SF Hassan - arxiv preprint arxiv:2410.09439, 2024 - arxiv.org
Motivated by the spin-2 nature of gravity, we consider a theory of N interacting spin-2 fields,
formulated in terms of vielbeins which have been argued to be free of the Boulware-Deser …
