Holography for the Trace Anomaly Action
Gregory Gabadadze, Massimo Porrati
A recently proposed effective action for the trace anomaly describes a tensor-scalar theory that is weakly coupled up to a certain high energy scale, where it becomes strongly inte…
Topological Gauging and Double Current Deformations
Sergei Dubovsky, Stefano Negro, Massimo Porrati
We study solvable deformations of two-dimensional quantum field theories driven by a bilinear operator constructed from a pair of conserved currents . We propose a quan…
A Supertranslation-Invariant Formula for the Angular Momentum Flux in Gravitational Scattering
Reza Javadinezhad, Massimo Porrati
The angular momentum radiated in gravitational scattering can be changed by performing a supertranslation of the asymptotic metric, i.e. by adding radiation with infinite wavelengh…
A Realization of Slow Roll Inflation and the MSSM in Supergravity Theories with New Fayet-Iliopoulos Terms
Hun Jang, Massimo Porrati
A new supergravity D-term, not associated to gauged R-symmetry, was recently discovered and used to construct new supergravity models. In this paper we use a generalization of the…
Back to the Future: Causality on a Moving Braneworld
Brian Greene, Daniel Kabat, Janna Levin +1
Brane observers executing appropriate motion through a partially compactified Lorentz invariant bulk spacetime, such as , can send signals along the brane that are…
Supertranslation-Invariant Dressed Lorentz Charges
Reza Javadinezhad, Uri Kol, Massimo Porrati
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of inf…
