Universe Colloquium: Brane induced gravity: Addressing the cosmological constant problem in more than five dimensions

by Florian Niedermann (LMU)

Wednesday 12 Jun 2013, 16:30 → 17:30 Europe/Berlin

Seminar room, basement (Universe)

Understanding the acceleration of the universe in a technical natural manner is a yet unresolved theoretical challenge. Since the acceleration is produced by sources of cosmological wavelength, a tempting approach is to consistently modify gravity at the largest observable distances. A consistent representative for a natural infrared modification is gravity induced on a 4-dimensional surface embedded in a higher-dimensional space-time of infinite extend. The five dimensional version of this theory is the DGP model. This talk will focus on the case of six and more dimensions. Both will be discussed, the consistency and phenomenological implications of this theory. The Universe Colloquium is followed by a social gathering with wine and cheese.
