Renormalization-group flow of the effective action of cosmological large-scale structures / Floerchinger, Stefan ; Garny, Mathias ; Tetradis, Nikolaos ; Wiedemann, Urs Achim
Following an approach of Matarrese and Pietroni, we derive the functional renormalization group (RG) flow of the effective action of cosmological large-scale structures. [...]

Fundamental partial compositeness / Sannino, Francesco ; Strumia, Alessandro ; Tesi, Andrea ; Vigiani, Elena
We construct renormalizable Standard Model extensions, valid up to the Planck scale, that give a composite Higgs from a new fundamental strong force acting on fermions and scalars. [...]

The Higgs of the Higgs and the diphoton channel / Kannike, Kristjan ; Pelaggi, Giulio Maria ; Salvio, Alberto ; Strumia, Alessandro
LHC results do not confirm conventional natural solutions to the Higgs mass hierarchy problem, motivating alternative interpretations where a hierarchically small weak scale is generated from a dimension-less quantum dynamics. [...]

First complete study of hadroproduction of a $\Upsilon$ meson associated with a prompt $J/\psi$ / Shao, Hua-Sheng (CERN) ; Zhang, Yu-Jie (Tsinghua U., Beijing, KLPRI ; Beihang U. ; CAS, Beijing)
We present the first complete study of $\Upsilon$ and prompt $J/\psi$ production from single-parton scattering, including the complete $\mathcal{O}(\alpha_S^6)$ color-singlet contribution, the $\mathcal{O}(\alpha_S^2\alpha^2)$ electroweak contribution, the complete non-relativistic S-wave and P-wave color-octet contribution as well as the feeddown contribution.
