Weyl and transverse diffeomorphism invariant spin-2 models in D=2+1

D. Dalmazi, A. L. R. dos Santos, Subir Ghosh +1

There are two covariant descriptions of massless spin-2 particles in $D=3+1$ via a symmetric rank-2 tensor: the linearized Einstein-Hilbert (LEH) theory and the Weyl plus transvers…
