Infrared divergences in dS/CFT

dS/CFT gives a perturbatively gauge invariant definition of particle masses in de Sitter (dS) space. We show, in a toy model in which the graviton is replaced with a minimally coupled massless scalar field, that loop corrections to these masses are infrared (IR) divergent. We argue that this implies anomalous dependence of masses on the cosmological constant, in a true theory of quantum gravity. This is in accord with the hypothesis of Cosmological SUSY Breaking (CSB).

More Thoughts on the Quantum Theory of Stable de Sitter Space
I review and update ideas about the quantum theory of de Sitter space. New results include a quantum relation between energy and entropy of states in the causal patch, which is satisfied by small dS
Pre-inflationary spacetime in string cosmology
Abstract Seiberg and Witten have shown that the non-perturbative stability of string physics on conformally compactified spacetimes is related to the behaviour of the areas and volumes of certain

Spinors and the AdS/CFT correspondence
We consider a free massive spinor field in Euclidean Anti-de Sitter space. The usual Dirac action in bulk is supplemented by a certain boundary term. The boundary conditions of the field are

We extend the method of calculation of propagators in maximally symmetric spaces (Minkowski, dS, AdS and their euclidean versions) in terms of intrinsic geometric objects to the case of massive spin
A new twist on dS/CFT
We stress that the dS/CFT correspondence should be formulated using unitary principal series representations of the de Sitter isometry group/conformal group, rather than highest-weight
Quantization of the massless minimally coupled scalar field and the dS/CFT correspondence
We consider the quantization of the massless minimally coupled scalar field in de Sitter spacetime. The no-boundary Euclidean prescription naturally picks out the de Sitter invariant vacuum state of

Quantum Gravity In De Sitter Space
We discuss some general properties of quantum gravity in De Sitter space. It has been argued that the Hilbert space is of finite dimension. This suggests a macroscopic argument that General

TLDR
The massless minimally coupled scalar field in de Sitter space is quantized, and a one-complex-parameter family of O(4)-invariant Hadamard Fock vacua which break de Sitters invariance is found.
Cosmological Breaking of Supersymmetry?
It is conjectured that M-theory in asymptotically flat spacetime must be supersymmetric, and that the observed SUSY breaking in the low energy world must be attributed to the existence of a nonzero
Non-Gaussian features of primordial fluctuations in single field inflationary models
We compute the three point correlation functions for primordial scalar and tensor fluctuations in single field inflationary models. We obtain explicit expressions in the slow roll limit where the
On the origin of supergravity boundary terms in the AdS /CFT correspondence
Abstract The standard formulation of the AdS/CFT correspondence is incomplete since it requires adding to a supergravity action some a priori unknown boundary terms. We suggest a modification of the
