Description:
Author(s): Eric A. Bergshoeff, Sjoerd de Haan, Olaf Hohm, Wout Merbis, and Paul K. Townsend We present a generally covariant and parity-invariant two-frame field (“zwei-dreibein”) action for gravity in three space-time dimensions that propagates two massive spin-2 modes, unitarily, and we use Hamiltonian methods to confirm the absence of unphysical degrees of freedom. We show how zwei-drei... [Phys. Rev. Lett. 111, 111102] Published Wed Sep 11, 2013
