Euclid. I. Overview of the Euclid mission / Euclid Collaboration
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. [...]

(GSSI, Aquila ; Gran Sasso) et al.
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. [...]

On the Soft Limit of the Large Scale Structure Power Spectrum: UV Dependence / Garny, Mathias (CERN) ; Konstandin, Thomas (DESY) ; Porto, Rafael A. (ICTP-SAIFR, Sao Paulo) ; Sagunski, Laura (DESY)
We derive a non-perturbative equation for the large scale structure power spectrum of long-wavelength modes. Thereby, we use an operator product expansion together with relations between the three-point function and power spectrum in the soft limit. [...]

Soft Pomeron in Holographic QCD / Ballon-Bayona, Alfonso (Porto U. ; Porto U., Astron. Dept.) ; Carcassés Quevedo, Robert (Porto U. ; Porto U., Astron. Dept.) ; Costa, Miguel S. (Porto U. ; CERN) ; Djurić, Marko (Porto U. ; Porto U., Astron. Dept.)
We study the graviton Regge trajectory in Holographic QCD as a model for high energy scattering processes dominated by soft pomeron exchange. This is done by considering spin J fields from the closed string sector that are dual to glueball states of even spin and parity. [...]

The Lagrangian-space Effective Field Theory of Large Scale Structures / Porto, Rafael A. (Princeton, Inst. Advanced Study ; DESY) ; Senatore, Leonardo (Stanford U., ITP ; KIPAC, Menlo Park ; CERN) ; Zaldarriaga, Matias (Princeton, Inst. Advanced Study)
We introduce a Lagrangian-space Effective Field Theory (LEFT) formalism for the study of cosmological large scale structures. Unlike the previous Eulerian-space construction, it is naturally formulated as an effective field theory of extended objects in Lagrangian space. [...]

The gravitational S-matrix / Giddings, Steven B. (UC, Santa Barbara ; CERN) ; Porto, Rafael A. (UC, Santa Barbara ; CERN)
We investigate the hypothesized existence of an S-matrix for gravity, and some of its expected general properties. We first discuss basic questions regarding existence of such a matrix, including those of infrared divergences and description of asymptotic states. [...]
