Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider at CERN / Franco Lima, Vinicius (CERN) /ATLAS Collaboration
Operational Experience and Performance with the ATLAS Pixel detector at the Large Hadron Collider at CERN ATLAS Collaboration The tracking performance of the ATLAS detector relies critically on its 4-layer Pixel Detector. As the closest detector component to the interaction point, this detector is subjected to a significant amount of radiation over its lifetime. [...]

The HEV Ventilator: at the interface between particle physics and biomedical engineering / Buytaert, Jan (CERN) ; Collins, Paula (CERN ; Liverpool U.) ; Abud, Adam Abed (CERN ; Liverpool U.) ; Allport, Phil (Birmingham U.) ; Álvarez, Antonio Pazos (Santiago de Compostela U., IGFAE) ; Akiba, Kazuyoshi (Nikhef, Amsterdam) ; de Aguiar Francisco, Oscar Augusto (CERN ; Manchester U.) ; Bay, Aurelio (Ecole Polytechnique, Lausanne) ; Bernard, Florian (Ecole Polytechnique, Lausanne) ; Baron, Sophie (CERN) et al.
A high-quality, low-cost ventilator, dubbed HEV, has been developed by the particle physics community working together with biomedical engineers and physicians around the world. The HEV design is suitable for use both in and out of hospital intensive care units, provides a variety of modes and is capable of supporting spontaneous breathing and supplying oxygen-enriched air.

First measurement of $Z \to \mu^+\mu^-$ angular coefficients in the forward region of $pp$ collisions at $\sqrt{s} = 13$ TeV / LHCb Collaboration
The first study of the angular distribution of $\mu^+ \mu^-$ pairs produced in the forward rapidity region via the Drell-Yan reaction $pp \rightarrow \gamma^{*}/Z +X \rightarrow l^+ l^- + X$ is presented, using data collected with the LHCb detector at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.1 $\rm{fb}^{-1}$. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. [...]

Measurement of $\tau _\text {L}$ using the ${B} _s^0 \rightarrow J/\psi \eta $ decay mode / LHCb Collaboration
Using a proton-proton collision data sample collected by the LHCb detector and corresponding to an integrated luminosity of 5.7 $\text{fb}^{-1}$, the lifetime of the $B_{s}^{0}$ mass eigenstate, $\tau_{L}$, is measured using $B_{s}^{0} \to J/\psi \eta$ decay mode to be $\tau_{L}$ = 1.445 $\pm$ 0.016(stat) $\pm$ 0.008(syst) ps. A combination of this result with a previous LHCb analysis using an independent dataset corresponding to 3 $\text{fb}^{-1}$ of integrated luminosity gives $\tau_{L}$ = 1.452 $\pm$ 0.014 $\pm$ 0.007 $\pm$ 0.002 ps, where the first uncertainty is statistical, the second due to the uncorrelated part of the systematic uncertainty and the third due to the correlated part of the systematic uncertainty..
