TH Cosmo Coffee

Technically naturalness in massive gravity

by Lavinia Heisenberg (Universite de Geneve)

Wednesday, 19 February 2014 from to (Europe/Zurich)
at CERN ( 4-2-011 - TH common room )
Description
There has been a successful non-linear covariant ghost-free generalization of Fierz-Pauli massive gravity theory, the dRGT theory. I will explore the cosmology in the decoupling limit of this theory. Furthermore, I will construct a Proxy theory to dRGT from the decoupling limit and study the cosmology there as well and compare the results. Finally, I will discuss the quantum consistency of the theory in great detail and show why the theory is technically natural.
