Axion Dark Matter: What is it and Why Now? / Chadha-Day, Francesca (Durham U., IPPP) ; Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Marsh, David J.E. (King's Coll. London)
The axion has emerged in recent years as a leading particle candidate to provide the mysterious dark matter in the cosmos, as we review here for a general scientific audience. [...]

Dark matter and the early Universe: a review / Arbey, A. (IP2I, Lyon ; CERN ; IUF, Paris) ; Mahmoudi, F. (IP2I, Lyon ; CERN ; IUF, Paris)
Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter and its nature, and demonstrate the close interplay between the cosmological properties of the early Universe and the observables used to constrain dark matter models in the context of new physics beyond the Standard Model..

Quantum Field Theories (QFTs) in Anti-de Sitter (AdS) spacetime are often strongly coupled when the radius of AdS is large, and few methods are available to study them. [...]

Non-abelian infrared divergences on the celestial sphere / Magnea, Lorenzo (CERN ; INFN, Turin ; Turin U.)
We consider the infrared factorisation of non-abelian multi-particle scattering amplitudes, and we study the form of the universal colour operator responsible for infrared divergences, when expressed in terms of coordinates on the `celestial sphere' intersecting the future light-cone at asymptotic distances.
