Pauli-Fierz mass term in modified Plebanski gravity
David Beke, Giovanni Palmisano, Simone Speziale
We study SO(4) BF theory plus a general quadratic potential, which describes a bi- metric theory of gravity. We identify the profile of the potential leading to a Pauli-Fierz mass…

Scalar-Tensor theory as a singular subsector of Λ(ϕ) Plebanski gravity
D. Beke
It is shown that, in the absence of matter fields, the coupling of a scalar field to the non-chiral Plebanski action can be obtained by relaxing the trace component of the simplici…
