Generalized Kerr-Schild gauge
Enrique Alvarez, Jesus Anero
The Kerr-Schild gauge is generalized to the case that the vector generating the deformation is not null. Contrary to naive expectations, this vector generates a finite expansion fo…
On the Weyl anomaly for chiral fermions
Enrique Alvarez, Luis Alvarez-Gaume, Jesus Anero +1
We compute the parity-odd part of the Weyl anomaly for chiral fermions in a background gravitational field. We start from a manifestly real form of the Lagrangian (that is, not onl…
One loop analysis of the cubic action for gravity
Enrique Alvarez, Jesus Anero, Carmelo P. Martin
We analyze some aspects of the cubic action for gravity recently proposed by Cheung and Remmen, which is a particular instance of a first order (Palatini) action. In this approach…
