ARRAY: An Open Source, Modular and Probe-Card based System with Integrated Switching Matrix for Characterisation of Large Area Silicon Pad Sensors / Pitters, Florian Michael (Austrian Academy of Sciences (AT)) ; Brondolin, Erica (CERN) ; Dannheim, Dominik (CERN) ; Kulis, Szymon (CERN) ; Maier, Andreas Alexander (CERN) ; Quast, Thorben (Rheinisch Westfaelische Tech. Hoch. (DE)) ; Sicking, Eva (CERN)
Silicon pad sensors are proposed as active material in highly granular sampling calorimeters of future collider experiments such as the Compact Linear Collider (CLIC) or the International Linear Collider (ILC). The electromagnetic section of these designs often include O(1000m2) of silicon pad sensors. [...]

Measurement of the production cross section for a Higgs boson in association with a vector boson in the $H \rightarrow WW^{\ast} \rightarrow \ell\nu\ell\nu$ channel in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
A measurement of the Higgs boson production cross sections via associated $WH$ and $ZH$ production using $H \rightarrow WW^{\ast} \rightarrow \ell\nu\ell\nu$ decays, where $\ell$ stands for either an electron or a muon, is presented. [...]

Stimulated emission of relic gravitons and their super-Poissonian statistics / Giovannini, Massimo (CERN ; INFN, Milan Bicocca)
The degree of second-order coherence of the relic gravitons produced from the vacuum is super-Poissonian and larger than in the case of a chaotic source characterized by a Bose-Einstein distribution. [...]
