Mini Symposium on Particle Cosmology: Scalar fields models of dark energy

by Carsten van de Bruck (University of Sheffield)

Wednesday 14 Nov 2007, 11:00 → 12:30 Europe/Berlin

Room 318 (LMU, Theresienstr. 37)

One of the major goals of cosmology and particle physics is to illuminate the origin and the properties of dark energy - a component that contributes about 70% of the total energy density in the universe and causes its expansion to accelerate. There are many open questions concerning dark energy, for example: How does it evolve in time? Does it interact directly with other matter forms in the universe? Are there any connections between dark energy and dark matter? In this talk I will discuss scalar field models of dark energy. I will focus in particular on the possibility of new interactions mediated by dark energy between cold dark matter particles and/or neutrinos.
