The Galileon: Where From? Where To?
  OKC/Nordita High-Energy Physics Theory seminar

Monday 01 November 2010
from 13:30 to 14:30
at CoPS group room (A5:1041)
Speaker : Claudia de Rham (Geneva University)
Abstract : The Galileon model introduced by Nicolis et al. is an extension of the decoupling limit of DGP, involving a relativistic scalar pi with specific derivative self-interactions. I will show how this model naturally arises in some limit of braneworld scenarios as well as in four-dimensional massive gravity, where the scalar pi plays the role of the helicity-0 mode of the graviton. I will then discuss some applications for early cosmology in a model of Galileon Inflation, as well as for late cosmology mentioning the implications for the late-time acceleration of the Universe.
