Weyl invariance with a nontrivial mass scale
Enrique Alvarez, Sergio González-Martín
A theory with a mass scale and yet Weyl invariant is presented. The theory is not invariant under all diffeomorphisms but only under transverse ones. This is the reason why Weyl in…
A note on the Gauge Symmetries of Unimodular Gravity
Enrique Álvarez, Sergio González-Martín, Carmelo P. Martín
The symmetries of Unimodular Gravity are clarified somewhat.
Conformal Dilaton Gravity: Classical Noninvariance Gives Rise To Quantum Invariance
Enrique Álvarez, Sergio González-Martín, Carmelo P. Martín
When quantizing Conformal Dilaton Gravity there is a conformal anomaly which starts at two loop order. This anomaly stems from evanescent operators on the divergent parts of the ef…
First Order formulation of Unimodular Gravity
Enrique Álvarez, Sergio González-Martín
First order lagrangians for the Weyl invariant formulation of Unimodular Gravity are proposed. Several alternatives are examined; in some of them first and second order are equival…
Unimodular Gravity Redux
E. Álvarez, S. González-Martín, M. Herrero-Valea +1
It is well known that the problem of the cosmological constant appears in a new light in Unimodular Gravity. In particular, the zero momentum piece of the potential does not automa…
