High Energy Theory Lunchtime Seminar
in 435 Physics
Speaker: Jose A.R. Cembranos, University of Minnesota
Subject: Gravitational Dark Matter
The modification of Einstein gravity at high energies is mandatory from a quantum approach. In this talk, I will point out that this modification necessarily introduces new degrees of freedom. We will discuss the possibility that these new gravitational states can provide the main contribution to the non-baryonic dark matter of the Universe. I will illustrate this idea with the simplest high energy modification of the Einstein-Hilbert action: R2-gravity.
