Slavnov-Taylor Identities for Primordial Perturbations
Lasha Berezhiani, Justin Khoury
Correlation functions of adiabatic modes in cosmology are constrained by an infinite number of consistency relations, which relate N+1-point correlation functions with a soft-momen…
Mixed Galileons and Spherically Symmetric Solutions
L. Berezhiani, G. Chkareuli, C. de Rham +2
It was previously found that in a certain parameter subspace of scalar-tensor theories emerging from massive gravity, the only stable field configuration created by static spherica…
Restricted Galileons
Lasha Berezhiani, Giga Chkareuli, Gregory Gabadadze
We study Galileon theories that emerge in ghost-free massive gravity. In particular, we focus on a sub-class of these theories where the Galileons can be completely decoupled from…
