The INFN R\&D: new pixel detector for the High Luminosity Upgrade of the LHC / Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) ; -FBK Pixel RandD Collaboration /ATLAS and CMS Collaborations
The High Luminosity upgrade of the CERN-LHC (HL-LHC) demands for a new high-radiation tolerant solid-state pixel sensor capable of surviving fluencies up to a few $10^{16}$~ particles/cm$^2$ at $\sim$3~cm from the interaction point. To this extent the INFN ATLAS-CMS joint research activity, in collaboration with Fondazione Bruno Kessler-FBK, is aiming at the development of thin n-in-p type pixel sensors for the HL-LHC. [...]

Search for heavy Higgs bosons $A/H$ decaying to a top quark pair in $pp$ collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector / ATLAS Collaboration
A search for heavy pseudoscalar ($A$) and scalar ($H$) Higgs bosons decaying into a top quark pair ($t\bar{t}$) has been performed with 20.3 fb$^{-1}$ of proton--proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = 8$ TeV. [...]

Study of $WW\gamma$ and $WZ\gamma$ production in $pp$ collisions at $\sqrt{s} = 8$ TeV and search for anomalous quartic gauge couplings with the ATLAS experiment / ATLAS Collaboration
This paper presents a study of $WW\gamma$ and $WZ\gamma$ triboson production using events from proton--proton collisions at a centre-of-mass energy of $\sqrt{s} = 8$ TeV recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb$^{-1}$. [...]

Analysis of the $Wtb$ vertex from the measurement of triple-differential angular decay rates of single top quarks produced in the $t$-channel at $\sqrt{s}$ = 8 TeV with the ATLAS detector / ATLAS Collaboration
The electroweak production and subsequent decay of single top quarks in the $t$-channel is determined by the properties of the $Wtb$ vertex, which can be described by the complex parameters of an effective Lagrangian. [...]

Electroweak Precision Measurements with Z Bosons at the LHC / Apyan, Aram (Fermilab) /ATLAS, CMS and LHCB Collaborations
Measurements of the forward-backward asymmetry in the neutral current annihilation process $q\bar{q} \rightarrow Z/\gamma^{*}\rightarrow \ell^{+}\ell^{-}$, where $\ell$ denotes a muon or electron, at the LHC are reported. The forward-backward asymmetry is measured as a function of the dilepton invariant mass yielding the effective weak mixing angle. [...]

Searches for new heavy resonances in final states with leptons and photons in ATLAS and CMS / Pandolfi, Francesco (Zurich, ETH) /ATLAS and CMS Collaborations
Searches for resonances in final states with leptons and photons have always been a powerful tool for discovery in high energy physics. We present here the latest results from the ATLAS and CMS experiments, based on up to 36~fb$^{-1}$ of 13~TeV proton-proton collisions produced at the Large Hadron Collider. [...]
