Null energy condition and superluminal propagation
S. Dubovsky, T. Gregoire, A. Nicolis +1
We study whether a violation of the null energy condition necessarily implies the presence of instabilities. We prove that this is the case in a large class of situations, includin…
Mirror World at the Large Hadron Collider
Riccardo Barbieri, Thomas Gregoire, Lawrence J. Hall
A mirror world can modify in a striking way the LHC signals of the Higgs sector. An exact or approximate Z_2 symmetry between the mirror world and our world allows large mixing bet…
D-type supersymmetry breaking and brane-to-brane gravity mediation
T. Gregoire, R. Rattazzi, C. A. Scrucca
We revisit the issue of gravitational contributions to soft masses in five-dimensional sequestered models. We point out that, unlike for the case of F-type supersymmetry breaking,…
