Galileon as a local modification of gravity

- A. Nicolis, R. Rattazzi, E. Trincherini
- Physics
- 13 November 2008

In the Dvali-Gabadadze-Porrati (DGP) model, the "self-accelerating" solution is plagued by a ghost instability, which makes the solution untenable. This fact, as well as all interesting departures… Expand

Bounding scalar operator dimensions in 4D CFT

- R. Rattazzi, V. Rychkov, E. Tonni, A. Vichi
- Physics
- 1 July 2008

In an arbitrary unitary 4D CFT we consider a scalar operator phi, and the operator phi(2) defined as the lowest dimension scalar which appears in the OPE phi x phi with a nonzero coefficient. Using… Expand

The Strongly-Interacting Light Higgs

- G. Giudice, C. Grojean, A. Pomarol, R. Rattazzi
- Physics
- 15 March 2007

We develop a simple description of models where electroweak symmetry breaking is triggered by a light composite Higgs, which emerges from a strongly-interacting sector as a pseudo-Goldstone boson.… Expand

Theories with Gauge-Mediated Supersymmetry Breaking

- G. Giudice, R. Rattazzi
- Physics
- 12 January 1998

Theories with gauge-mediated supersymmetry breaking provide an interesting alternative to the scenario in which the soft terms of the low-energy fields are induced by gravity. These theories allow… Expand

Causality, analyticity and an IR obstruction to UV completion

- A. Adams, N. Arkani-Hamed, S. Dubovsky, A. Nicolis, R. Rattazzi
- Physics
- 20 February 2006

We argue that certain apparently consistent low-energy effective field theories described by local, Lorentzinvariant Lagrangians, secretly exhibit macroscopic non-locality and cannot be embedded in… Expand

Strong Interactions and Stability in the DGP Model

- M. Luty, M. Porrati, R. Rattazzi
- Physics
- 12 March 2003

The model of Dvali, Gabadadze, and Porrati (DGP) gives a simple geometrical setup in which gravity becomes 5-dimensional at distances larger than a length scale lambda(DGP). We show that this theory… Expand

Quantum Gravity and Extra Dimensions at High-Energy Colliders

- G. Giudice, R. Rattazzi, J. Wells
- Physics
- 10 November 1998

Recently it has been pointed out that the characteristic quantum-gravity scale could be as low as the weak scale in theories with gravity propagating in higher dimensions. The observed smallness of… Expand

Classical and Quantum Consistency of the DGP Model

- A. Nicolis, R. Rattazzi
- Physics
- 21 April 2004

We study the Dvali-Gabadadze-Porrati model by the method of the boundary effective action. The truncation of this action to the bending mode π consistently describes physics in a wide range of… Expand

Electroweak symmetry breaking after LEP1 and LEP2

- R. Barbieri, A. Pomarol, R. Rattazzi, A. Strumia
- Physics
- 5 May 2004

In a generic “universal” theory of electroweak symmetry breaking, simple symmetry considerations and absence of tuning imply that heavy new physics affects the lowenergy data through four parameters.… Expand

Gaugino mass without singlets

- G. Giudice, M. Luty, H. Murayama, R. Rattazzi
- Physics
- 21 October 1998

In models with dynamical supersymmetry breaking in the hidden sector, the gaugino masses in the observable sector have been believed to be extremely suppressed (below 1 keV), unless there is a gauge… Expand
