The diphoton as the Higgs of the Higgs / 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. [...]

Towards the compression of parton densities through machine learning algorithms / Carrazza, Stefano (CERN) ; Latorre, José I (Barcelona U., ECM)
One of the most fascinating challenges in the context of parton density function (PDF) is the determination of the best combined PDF uncertainty from individual PDF sets. [...]

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.

Maximal Flavor Violation in Super-GUTs / Ellis, John (King's Coll. London ; CERN) ; Olive, Keith (Minnesota U., Theor. Phys. Inst) ; Velasco-Sevilla, Liliana (University of Bergen, DPT)
We consider supersymmetric grand unified theories with soft supersymmetry-breaking scalar masses $m_0$ specified above the GUT scale (super-GUTs) and patterns of Yukawa couplings motivated by upper limits on flavour-changing interactions beyond the Standard Model. [...]
