Ghosts & Matter Couplings in Massive (bi-&multi-)Gravity
Claudia de Rham, Lavinia Heisenberg, Raquel H. Ribeiro
Recently, several works have investigated the coupling to matter in ghost-free massive (bi-&multi-)gravity and a new effective coupling to matter has been proposed. In this note we…
On couplings to matter in massive (bi-)gravity
Claudia de Rham, Lavinia Heisenberg, Raquel H. Ribeiro
We investigate the coupling to matter in ghost-free massive (bi-)gravity. When species in the matter sector couple covariantly to only one metric, we show that at one--loop these c…
Riding on irrelevant operators
Claudia de Rham, Raquel H. Ribeiro
We investigate the stability of a class of derivative theories known as and Galileons against corrections generated by quantum effects. We use an exact renormalisation group…
The effects of a fast-turning trajectory in multiple-field inflation
Maciej Konieczka, Raquel H. Ribeiro, Krzysztof Turzynski
The latest results from PLANCK impose strong constraints on features in the spectrum of the curvature perturbations from inflation. We analyse the possibility of particle productio…
